The cobblestone Akbıyık Caddesi (Road) is one of the few places to head to for a nightcap in Sultanahmet. The street is lined with cafes and bars sporting comfy Turkish divans (cushion lounges) and chilled-out tunes. Enthusiastic staff will welcome travelers wishing to relax with a beer or wine until late, but most venues will start to close around 1am to lessen the noise for nearby hotels. Don't expect wild nights—it's a laid-back vibe.
If you don’t want to venture far from your hotel in Sultanahmet, then this street offers a good variety of late-night drinking options, otherwise head to Şah Bar on İncili Çavuş Sokak. Dancing until dawn or listening to live music is best in Beyoğlu and Şişli across the Golden Horn in the entertainment precincts of Taksim, Asmalımescit, Galatasaray, Ortaköy or Kuruçeşme.
