This is one of my favorite bars in Manhattan. It has a courtyard in the middle and they only serve a large selection of Belgian beer. It's always dark with red lights so it's like a giant darkroom with everyone developing hangovers instead of film. The courtyard creates a front bar that is open on the weekends, so if you get cornered talking about architecture you can escape over to the front bar and watch people walk down 4th street.
The operators of the Peter Pan bakery make the best donuts I've ever tasted. This place is charming to its core. Decor and presentation: circa 1971 & virtually unchanged since.
It's a sweet agave bar hidden in the fridge of a Mexican grocery store that use to be a laundromat. It doesn't get more Brooklyn than that but the tourists haven't found it yet so I highly recommend it. Music is really good and they have a great selection of mezcal. Felipe, the owner, also owns the adjoining restaurant Cerveceria.
