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.
Arthur Avenue is a mainstay of the Bronx. Since the early 1900's til today, it's been the hub of the Italian-American community that calls the Bronx home. Many family-owned, traditional businesses dot the main avenue, and the food culture is rich and boisterous.
