Pdero's Place is pretty good, they have a great $4 cuban sandwich and tasty fruit shakes.

That said, it's no where near as good as El Sabroso. They have only been open a month and I've eaten there about seven times. It's the only place I know that actually closes early on Friday because they have RUN OUT OF FOOD. There is a constant line of about a dozen people at the counter and the tables are always filled. The wait staff are pretty slow, but they are super-friendly so it works out in the end. There is no better eatery in the Heights.
