Busy.
This is a very broad question. Compared to what? The downstairs gets busy where it's hard to move around when it's late and the bands are really going. The upstairs also gets busy as does the back patio. It also depends on time of year and what's going on in the city. I'm sure this doesn't help, try asking a more focused question and people can help better. This place is popular
