I went to Gran Sabana last night, the Latino/Carribean place in the strip mall on the SE corner of 55/54. I had the Pabellon (ropa vieja-shredded beef- with a fried egg on top). It was a little stringy (isn't ropa vieja always a bit stringy), but good flavor and I loved the egg on top. The salsa was spicy and make sure you ask for the salsa verde, too, it has a great mild, lime flavor.
My friends ordered arepas (kind of a thick corn-based pita) which were good. Lots of other things looked tasty.
I'd like to try out the Jamaican place next door, and Antojitos, the El Salvadorean (?they have Pupusas which I think of as traditionally El Salvadorean) place next to that. I'd love to hear reviews if anyone has been.
