Baku's nightlife runs the range from Soviet-era teatr buffets to slick oil-boom cocktail bars. The Old City and the streets around A. Alizade Street are the most walkable drinking strips, with a cluster of expat-friendly pubs drawing heavily from the oil and gas community. Theatres, opera, and ballet are a genuine evening option too — performances in both Azeri and Russian, and prices are low by European standards. Check dress codes for the grander venues; most places are casual, but some are not.
