Mostly locals like this place because of beer, but I go there for their shots! Beautiful flavoured vodka shots! Orange, mango, pineapple, ginger, apple pie flavours! Each shot is only for 2 manats and you can get a set even for less. Although the place is famous for its drinks, they serve good and cheap food. Club sandwich is only 5 manats.
You should visit this place if you wish to try some local places, hidden from tourists, but still in the very centre of Baku. Staff is very friendly, not sure if they speak English, but I'm sure you will like them. Background music is usually nice, but can be creepy sometimes.
Try pomegranate tequila!
