We checked out Henry Public (Henry St. b/w Atlantic and Pacific in Cobble Hill) last night. It was the first night open, and the place was already busy. The transformation of the space from its former incarnation as a tv repair shop is amazing. You would think it had always been a pub. The lighting is dim and the music is mostly jazz. There's a smallish bar area and a few booths in the front room and tables in the small back room.
We tried the burger, which was very good (grass-fed beef ground on premises, and cooked to order). The food menu is limited here; the drinks seem to be the main thing. The cocktail list has some interesting house creations, and they have several beers on tap (I had an extremely fresh Six Points Oatmeal Stout).
This place is a welcome addition to the neighborhood -- definitely worth a look if you're in the area.
