Kadıköy is the main hub of the Asian side and one of the best places to watch everyday Istanbul at work, well away from the tourist crowds. The central market area, Kadıköy Çarşısı, is a network of narrow streets packed with fishmongers, spice shops, second-hand bookstores, vintage clothing stores, and grocery stalls. Food is the district's strong suit: good street food, budget eateries, and restaurants that draw people across the water. The bar scene centers on Kadife Street, known locally as Barlar Sokağı, and spills over into Moda, where the seaside promenade fills up around sunset. Prices are lower than the European side, and the welcome is warm.

The collections here cover both the Byzantine and Ottoman periods. Many objects are more than a thousand years old and well preserved. Seeing them side by side shows how much the two cultures borrowed from each other.

Visitors interested in Byzantine and Ottoman architecture will want extra time here. Photographers usually come early, before the crowds arrive and while the light is low.

First-time visitors and solo travelers both manage easily here. The area is walkable, and staff at most sites are used to tourists.

Nearby bazaars sell Turkish crafts and souvenirs. Tea houses in the side streets are a good place to rest between sights.
