Despite the annoying 3-PM-reservation policy, once inside the drinks are pretty damn good. Sadly, there can be a pretty dramatic variation of quality depending on the bartender. The bacon bourbon drink is great; their gin fizzes are good when made right; the addition of a chihuahua dog is awesome.
The service is pretty good. The crowd is pretty good and because they keep the numbers low it doesn't get too crowded or too loud.

Edit: In recent months they have greatly expanded their drink menu, and I think at this point they are one of the top libation destinations in the city.
