Nice speakeasy vibe with a very knowledgable bartender who made a mean caipirinha and also knew the proper way to pronounce the Brazilian rum cachaca (unlike the fellow beside me who also ordered one and pronounced it like cha-cha-cha) as well as the subtle differences between the two he had at his disposal (Leblon and Cabana).
Bonus points for having a table alongside the entrance watching newbies through the window fumble around trying to figure out how to enter through the elusive metal door with no handle or label (high unintentional comedy).
Minus one star for having a "Bartending for Dummies" book in plain sight next to the liquor rack (pretty sure it was not intentionally placed there to be ironic)
