First timer, know nothing about Puerto Rican food. Met up with old college buddy who hails from Puerto Rico and says food here is authentic. All I know if it was delightful, I am sure a lot of it had to do with my companion.
It's a real dive hole in the wall, way too loud with very few patrons, hard to carry on a conversation and we were as far away as we could be from the only other table of guests. Voices bouncing off the walls.
Give it a try and see what you think.
