El Floridita

Open 24 hours in Washington Heights, this diner serves Cuban and Dominican dishes around the clock, and the reason to go is the Cubano: ham, pork roast and Swiss cheese pressed between crisp bread with a layer of pickles. The wider menu runs to mofongo, asopao and rotisserie chicken, though the chicken doesn't quite match the sandwich's consistency. The room is kept simple and clean by the restaurant's own description, making it a reliable late-night stop rather than a destination in itself.
