I came here late on a Saturday night and was pretty happy to find a place with the following:
1. Good beer selection
2. Food until midnight (I think?)
3. No cover charge (but no live music either)
Its a pretty cool place to hang out and catch up with people as most of the bars in the Kensington market area are smaller/darker/louder than Trinity Common. There's no cover charge but there are lots of bars in the area that have live music.
When I went, the crowd was pretty much all college aged. This may or may not be your thing if you are bar hopping in this area.
