What you loved an hour ago may not be on the list for your next round; the beer list here is printed on paper, because it sometimes changes multiple times in a day to accommodate limited-production brews. But with 32 rotating taps and 25 to 30 bottles in the mix, at this spot—which has been a tavern nearly continuously since just after the Civil War—there is always a new beer you’ll want to try.

Gulu Gulu Café
A multitude of taps offer up beers that you just won’t find anyplace else, and an app to track membership in the Flying Gulu Beer Society will please even the most pretentious craft brew drinker.
