Hangar is a place where you can have a couple of good beers, watch football or rugby year round (they broadcast almost all the top matches one would like to watch), enjoy a pub atmosphere, and in general spend time in a nice place in the very city center.
Sports fan or not, you will feel good there: the atmosphere is very relaxed, even though Shavteli street is kinda touristic. Prices are very acceptable, so you can sip beer, eat some tasty beer snacks and watch people passing by.
In summertime there is also live music there.
