Four stars is for the seating and feel of the place, as well as attentive bartenders both times I've been. I think the generous-sized couch/lounge thing is the complement this place offers compared to other downtown spots. It makes for a good meet-up location when you have a decent-sized crew.
I might be a cheapskate, but the beer is a bit pricey ($3.50 for a PBR = the R word. I know Pabst advertises on NPR an all now, but it's still the same swill).
