Just left Rock Bottom for lunch and the beer was very good (although the food left something to be desire). They had a Munich Golden lager (good) and three IPAs (Prussia, Sub Zero [w/ Simcoe hops], and St. Nick's). The St. Nicks was the most profound (SG 16.5) while the Sub Zero was also interesting and challenging. The Prussia I also liked a lot. They also had a stout and an amber that were solid. Overall this place is now neck and neck with Iron Hill IMHO.
