Casa B has two different spaces: a small bar upstairs where the bartender might shuffle through David Bowie songs for you all night, and a dining room in a windowless basement downstairs, which - thanks to greenery, walls made of wine racks, and a lot of energy - is a much more fun than windowless basements tend to be. In either spot you can enjoy a mostly Spanish menu of both tapas and large plates. We like to stick with the small plates, particularly the grilled squash with honey chili and shallots.
