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.
Chuko has the best vegetarian ramen I've ever had. It's kind of ruined me for other types of Ramen. Favorite neighborhood spot with good people running it.
