In Istanbul, history and tradition are piled 
    layer upon layer. Stately palaces, mosques and cathedrals lie beside chaotic 
    bazaars, steaming hamams and poky nargile (hookah) joints.
                Ottoman 
                Constantinople sits easily with ancient Byzantium, but emerging on top of 
    them is a new stratum: Istanbul the cool. 
                In the past decade, development has 
    transformed ghetto-like no-go zones into hip and vibrant neighbourhoods 
    whose stylish clientele spill out into the streets, eating and drinking 
    until the small hours. Clubs, bars, cafes, restaurants, shops, hotels and 
    galleries are springing up at an explosive pace. 
                If you go to Istanbul expecting belly dancers, you might be surprised to 
    find yourself watching the sunrise at a nightclub on the Bosphorus; if you 
    imagine a diet of greasy kebabs, you'll be stunned at the range of haute 
    cuisine options fusing traditional Turkish food with cutting-edge 
    international styles. And if your idea of shacking up in Istanbul is a 
    second-rate pension, you'll be amazed at the range of chic, sassy and 
    downright sexy boutique hotels you can stay at. 
                Istanbul will be a European Capital of 
    Culture in 2010 and now that the first low-cost flights there have been 
    launched by Easyjet, hip weekenders will be flocking to soak up the 
    excitement. Here's what they need to know: 
                Boutique boltholes 
                
                Istanbul inherited some rich pickings from 
    its Ottoman ancestry in terms of palaces and mansions, and a great many have 
    been restored and converted into residences, clubs, restaurants and boutique 
    hotels. A frontrunner of the genre is the gorgeous A'jia (00 90 216 
    413 9300;
    www.ajiahotel.com), the former 19th-century residence of a governor of 
    the city. This peaceful and secluded mansion, up the Bosphorus strait on the 
    Asian shore, is blissfully remote from the city centre. It has 10 deluxe 
    rooms and six suites, most of which have views out on to the water and some 
    with private terraces. Prices per night start at around €290 (£196). You can 
    take a boat from the hotel across to the nightlife on the livelier European 
    side, or profit from A'jia's own excellent restaurant, which serves 
    international and Mediterranean cuisine. 
                For something a little closer to the 
    action, check out the Sumahan on the Water (00 90 216 422 8000;
    www.sumahan.com), with rooms from €170. Also on the Asian side, near the 
    towering Bosphorus suspension bridge, this hotel is in the old wooden-housed 
    village of Cengelkoy, next to a site that used to be a distillery that made 
    raki (an aniseed-flavoured aperitif) in Ottoman times. Some rooms come with 
    a private hamam (Turkish bath), while guests can use the hotel's boat as a 
    ferry to the city's main transport hubs. 
                Facing the Sumahan on the European side is 
    the spanking new Hotel Les Ottomans (00 90 212 287 1024;
    www.lesottomans.com), a high-end phenomenon. Built inside an Ottoman 
    yali (a luxurious wooden mansion), the interior and 12 luxurious suites 
    (starting at €1,200) are decked out in lavish Ottoman style. The outdoor 
    pool has a transparent floor panel that doubles as a spectacular ceiling in 
    the swish subterranean spas. 
                Popularly assumed to be Istanbul's finest 
    digs, the five-star Four Seasons Hotel (00 90 212 638 8200;
    www.fourseasons.com/istanbul) in Sultanahmet, with rooms from €290 a 
    night, inhabits a conversion of another variety. 
                Set in the grounds of a former prison, 
    which was functioning for petty criminals until the end of the Seventies, 
    its range of rooms and suites, gazebo-style restaurant and expertly 
    manicured gardens are almost worth getting banged up for. 
                On a more modern note, city slickers might 
    prefer the new Sofa Hotel (00 90 212 368 1818;
    www.thesofahotel.com) in the middle of Istanbul's trendy Nisantasi area. 
    Nestled among the city's designer shops, including Armani, Gucci (and also 
    Marks & Spencer), it's a minimalist-chic urban option. Nightly rates start 
    at around €200. 
                Chic eats 
                
                If your idea of Turkish dining is tucking 
    into slices of greasy meat carved off a cylindrical spit, ingested on a 
    pavement after eight pints of beer, then think again: Istanbul is brimming 
    with stylish restaurants. 
                The city's smart staple is the multiple 
    award-winning 360 (00 90 212 251 10 42;
                www.360istanbul.com): a glass-walled rooftop extravaganza with a popular 
    bar and a circular view of the metropolis. The culinary influences hail from 
    all around the world, and dishes include delicious Lebanese kibbe meatballs 
    stuffed with walnuts, veal-and-prawn surf and turf or lamb loin confit, 
    expertly poached in olive oil for five whole hours. 
                Alternatively, head up the Bosphorus to 
    Ortakoy, one of outer Istanbul's quaintest villages and hottest nightspots, 
    and the Banyan Ortakoy (00 90 212 259 9060). Sit on the terrace 
    beside the tiny banyan trees if the weather's still warm enough and feast on 
    their Oriental delights while gaping at the stunning view of the neo-Baroque 
    waterside mosque. Another option in this part of town is Erguvan (00 
    90 212 327 6075) in the newly built Radisson SAS hotel, also on the 
    waterfront and perfect if you fancy fresh seafood. 
                This year's hot-off-the-press destination 
    is Mikla (00 90 212 293 5656), perched on top of the Marmara Pera 
    Hotel in the thick of the famous Old Pera neighbourhood. It has views to die 
    for, food to match (the lamb escalope is a must) and a verdant rooftop bar 
    complete with swimming pool for those sweltering summer nights. Reservations 
    are advised at all the restaurants featured here, and meals with wine 
    average around €50 (£35) a head. 
                Bar life 
                
                You might be offered endless cups of cay, 
    the local tea, from ultra-friendly locals by day, but only a concerted 
    survey of the city's bar circuit by night will reveal what Istanbul really 
    has to offer in terms of a good bottoms-up. For beer, try the ubiquitous 
    native brew, Efes. Turkish wines generally have a lot to answer for in the 
    hangover stakes; however, there is one diamond in the rough and that is the 
    Sarafin brand, available in red and white varieties in most good restaurants 
    and bars. 
                A fine place to start an evening's jaunt is 
    at the local favourite Leb-i Derya (00 90 212 293 4989;
    www.lebiderya.com), an effortlessly chilled establishment featuring 
    fantastic views and an extensive cocktail list, including the notorious 
    Balalaika, Caipirovska and Monday concoctions. 
                Zoe (00 
    90 212 251 7491) is another venue in Taksim that makes the most of the 
    city's incredible vistas. In colder weather you can hang out in the stylish 
    bar area, but join the crowd on the roof to party under the stars in the 
    summer. 
                Also very popular with Istanbullus is the
                Nu Pera (00 90 212 245 5810), an umbrella name for a constellation of 
    joints housed in the same building. During the summer months, attention is 
    focused on the rooftop terrace, for which you'll certainly need a 
    reservation at weekends. But be aware of the door policy: as with many clubs 
    and bars in the city, men are rarely granted entry if not accompanied or 
    outnumbered by females, and smart, fashionable dress is essential. There's 
    also been a recent rise in the number of requests to see passports at the 
    door. 
                If you prefer something a little more laid 
    back, check out Cezayir (00 90 212 245 9980;
    www.cezayir-istanbul.com). Housed in a 100-year-old school building, 
    this chic cafe, bar and restaurant is composed of a number of rooms of 
    varying levels of noise and energy, with sofas, a dancefloor and great 
    mojitos. 
                Club hits 
                
                Travel before the beginning of October and 
    you'll catch the city's infamous Bosphorus nightclubs: outdoor complexes of 
    restaurants, bars and dancefloors right on the water, with a refined 
    clientele who park their yachts alongside the private docks and make their 
    entrances like royalty. The most prominent of these is the world-class Reina (00 90 212 259 5919), for which you'll need to book ahead if you 
    want a table, and the female-accessory rule applies to appease the 
    stony-faced bouncers. Blackk (00 90 212 236 7256;
    www.blackk.net) is just across the road, and open year-round. Excelling 
    in sumptuous decor, it's an eating, drinking and dancing venue with a moody, 
    dark-leather interior and an open conservatory designed in the most lavish 
    rococo upstairs. 
                If serious dancing is your thing, get down 
    and boogie in an original Seventies disco, Godet (00 90 212 243 
    8143). This late-night venue on top of the Surmeli Hotel rarely gets going 
    until well after midnight and has garnered a reputation for its innovative 
    DJs. 
                For live music, head to the number one 
    concert spot, Babylon (00 90 212 292 7368;
    www.babylon-ist.com), an unpretentious and intimate venue which has 
    hosted scores of international ensembles including The Fall, and Stereolab.
                
                Classic must-sees 
                
                The morning after, you may want to tick off 
    a few of the classic sights, and for these head to the historical district 
    of Sultanahmet. Don't miss the 
                Aya Sofya 
    (00 90 212 528 4500), formerly known as the 
                Hagia Sophia, 
    which was the biggest cathedral in the world for 1,000 years and has a 
    splendid vast dome, or its giant neighbour, the 
                Blue 
    Mosque (00 90 212 518 13 19) with its six minarets. 
                Within walking distance of the two is 
                Topkapi Palace 
    (00 90 212 512 0480). Set in the gardens of Gulhane park, the palace is a 
    network of stunning, perfectly preserved tiled and marbled buildings that 
    accommodated official events and the private residences of the Sultanate in 
    the days of the Ottoman Empire. 
                The Basilica Cistern is an old Roman 
    well that was used for storing water channelled into the city along an 8km 
    system of aqueducts from nearby Belgrade forest. Don't just expect a hole in 
    the ground: the Cistern was used as a set for From Russia With Love and is 
    the size of a cathedral, with more than 300 supporting columns and 80,000 
    cubic metres of water. 
                The 
                Grand Bazaar is a shopping 
    experience par excellence. The giant covered market, the centre of which 
    dates back to 1461, twists and turns, and can swallow you whole if you're 
    not careful. Aside from the belly dancing outfits, ornate mirrored caps, and 
    fake labels, it's worth checking out the selection of pashminas, jewellery, 
    and leather jackets and handbags. 
                Alternative must-sees 
                
                After the rabble of touts and salesmen at 
    the Grand Bazaar you might crave a more subdued shopping experience, so hop 
    on the metro at Taksim Square and go a couple of stops to Istanbul's latest 
    retail wonder: the Kanyon mall in Levent. This is not your average 
    enclosed American-style colossus: it's a climate-controlled outdoor complex 
    in the form of a canyon, with towers and cooling or warming breezes, 
    depending on the season. 
                To escape the spending trap, flee the 
    mainland altogether on a ferry from Eminonu, Kabata or Bostanci ports (www.ido.com.tr) 
    to one of the four Princes' Islands in the Sea of Marmara. The trip 
    takes an hour-and-a-half at most, and you can disembark at any one of the 
    relaxing little isles. Buyukada (literally, 'the big island') has, like all 
    the others, forsaken motorised vehicles (with the exception of the 
    startlingly numerous emergency services) in favour of bicycles, horses and 
    donkeys. If you have time, take a ride up the road strewn with prayer 
    ribbons to St George's Monastery, go for a walk among the trees or just 
    chill out in one of the cafes in the main village, like the trendy new Gr.ile (00 90 216 382 1630). 
                
                Back in the city centre, another 
    fascinating and less frequented spot is the Galata Mevlevihanesi (00 
    90 212 245 4141), an old Sufi lodge converted into a museum. If you're there 
    on a Sunday or the first or last Saturday of the month, buy a ticket for the 
    Sema ceremony and get dizzy watching the renowned whirling dervishes, who 
    chant and spin in meditation for up to an hour. 
                The Istanbul Modern (00 90 212 334 
    7300;
    www.istanbulmodern.org) is the city's first institution dedicated to 
    contemporary art. Situated in a former shipping warehouse by the docks, it 
    houses a permanent collection of Turkish art from the last century, as well 
    as an upcoming exhibition of picks from the last Venice Biennale that will 
    be showing towards the end of 2006. 
                To experience the best of Bosphorus village 
    life, travel north along the strait from the museum between the two giant 
    suspension bridges that connect Europe to Asia, to the buzzing Sunday market 
    in Ortakoy and the fishing village of Arnavutkoy. One of the best walks in 
    Istanbul is along the Bosphorus from Arnavutkoy to the old castle at Rumeli Hisari, past scores of fishermen and great fish restaurants, 
    boats and yachts and a fantastic view of the tankers travelling to and from 
    the Black Sea, with the glittering backdrop of the Asian continent just 
    across the water. 
                Istanbul insider 
                
                My favourite place is also my home: 
                Cihangir, a section of Beyoglu that's undergone a facelift. I am drawn 
    by the fact that it is cosmopolitan, multicultural, central, and for 
    professional reasons, since there are many actors, writers, directors and 
    producers in the area. There's also a good number of foreigners with flats 
    here. 
                The main street has a few very popular 
    cafes including Leyla, Porte, the excellent fish restaurant Doga Balik and 
                Miss Pizza. My favourite cafe is Smyrna, 
    which has kooky decoration. It's the kind of place where you feel like 
    you'll always bump into someone you know.
