This place is awesome. The outside looks pretty sketchy but it's always packed and for good reason. They have so many types of beer on tap and bottle.
Its a fairly small place so tables go fast and depending on the time wait times can be anywhere from 1-3 hours. It's not that bad because you can stand around and order drinks while you wait. If there's other space available either at a standing table or right at the bar they 'll move you over till a table is ready.
Service is great, they do their best to accommodate you. If you go in a group, you will be waiting for a long time.
The food is also really good. The burger is massive, awesome value and tastes great.
You should definitely give this place a try.
