This place is great for after work meetups. You can sit on a long table and get acquainted with other people while you are having fun. They offer a variety of both local and international beers and also quick bar food. You can eat traditional Turkish bar food as well as hot dogs & burgers.
Beer Hall has a very distinct interior with long wooden tables and string light hanging down from the ceiling. The place can host around 200 people but they can be really busy after working hours (6-9pm). It is a self service place so you should find a seat first and then look for your desired drink (beer is recommended) or food.
You have to try traditional Turkish beers, Bomonti and Tuborg.
