About Istanbul
City overview
Istanbul is the only city that sits on two continents — the Bosphorus strait splits the European and Asian sides — and it has been the capital of three empires (Roman, Byzantine, Ottoman) over 1,700 years. The historic peninsula at Sultanahmet holds the Hagia Sophia and Topkapı Palace; cross the Galata Bridge into Beyoğlu and the city pivots into 19th-century European Pera and modern Taksim; cross the Bosphorus by ferry and you're in Asia, in Kadıköy's market streets.
Food & drink
Turkish breakfast (kahvaltı) is a long communal table — eggs, olives, cucumber, tomatoes, white cheese, jams, simit (sesame rings), and endless tea. Lunch is döner from a vertical spit (the original, not the Berlin variant) or pide (boat-shaped Turkish pizza); evenings move to meyhanes for mezes and rakı, or to a fish restaurant along the Galata Bridge or Kumkapı. Balık ekmek (fresh fish sandwich) from the bobbing boats at Eminönü pier and karadeniz pidesi (Black Sea-style cheese-filled pide) are the cheap classics; baklava at Karaköy Güllüoğlu is the splurge.

Neighborhoods
1Beyoğlu (Galata, Pera, Taksim)
Across the Golden Horn — 19th-century European-style buildings, İstiklal Avenue (1.5km pedestrian shopping street ending at Taksim Square), Galata Tower, rooftop bars over the Bosphorus. The city's nightlife heart.
2Kadıköy (Asian Side)
Locals' favourite — Tuesday market, fish-restaurant row at Çiya Sofrası's neighbourhood, street art, third-wave coffee. 20-minute ferry from Eminönü; the route itself is half the experience.
3Karaköy
At the foot of the Galata Bridge on the Beyoğlu side — galleries, third-wave coffee, design shops, and balık ekmek (fish sandwich) boats grilling fresh mackerel on the waterfront.
Day trips
1.5h by ferry from Kabataş or Eminönü
Princes' Islands (Adalar)
Car-free islands in the Sea of Marmara — Büyükada is the largest. Wooden Ottoman-era mansions, horse-drawn phaetons (until recently; now electric carts), pine-shaded beaches. Best as a full day.
2.5h via IDO sea-bus from Yenikapı to Bursa, then short bus or taxi
Bursa
The first Ottoman capital — Green Mosque, Green Tomb, Uludağ mountain ski resort, and the original İskender kebab (named after the 19th-century Bursa chef who invented it).
2.5h by bus from Esenler Otogar
Edirne
Former Ottoman capital before Istanbul, near the Greek and Bulgarian borders. The architect Sinan's Selimiye Mosque (UNESCO) is widely considered his finest work — quieter than anything in Istanbul.
Getting around
Buy an İstanbulkart (₺50 deposit at any station) — works on the T1 tram (the tourist artery from Kabataş through Sultanahmet to Bağcılar), the Marmaray underwater rail, the M2 metro, every ferry, and most buses. Ferries across the Bosphorus and Golden Horn are the most enjoyable way to move — Eminönü ↔ Kadıköy is the signature 20-minute crossing. Taxis are cheap by global standards but Yandex (the Russian Uber clone) gets you a metered price up-front.
