Having just returned from La Cabana Rodriguez aka Rodriguez Fried Chicken, I can say with utmost confidence that the beef tripe stew is pretty damn good. Lots of earthy tasting tripe, some lean so to speak, some fatty, all in nice size strips and chunks. Put that in a tomato based liquid with a hint of vinegar and some potatoes and cilantro and you're good to go. Add lemon and hot sauce provided by your waitress and you're definitely set. My only gripe about the bowl of stewed tripe is the potatoes were a little bland tasting.

Cafe Rubio, Northern Blvd (98th St.??), Jackson Heights,
They make an excellent dominican style mofongo with shrimp. Not your typical pork mofongo but it is really good. I would appreciate any other suggestions for good cheap mofongo in Queens.

Second Casa Adela, also Cibao in Manhattan on Rivington & Clinton has an excellent mofungo (also great Cubanos, FWIW...)
Casa del Mofungo is fun in that you can get 100 different things on your mofungo, but otherwise not worth going out of one's way for. Unless you live near it to begin with, I wouldn't bother.
I really, really dig the seafood mofongo at Sofrito in Midtown East. If you're willing to endure deafening salsa and walkie talkie-wielding hosts and having to shout at your companions across the table, this stuff is worth it. Recommended by a Puerto Rican cab driver who grew up in NYC.

El Comal at 148-62 Hillside Ave in Jamaica specializes in papusas, but also serves mofongo.
There is a cuchifritos place on 5 ave in Brooklyn between 49 St/50 St. The prices on the menu in the window were very reasonable.
