El Aguila Competition may be stiff in Spanish Harlem, but one of its most beloved Mexican restaurants is El Aguila. Is it the gargantuan helpings of meat, beans, and rice? The taco al pastor special, two tacos for $2? The fact that it’s open 24 hours a day? You could try to figure it out, or you could roll home from 116th Street, stuffed beyond belief.El Aguila, 137 East 116th Street (at Lexington Avenue); 212-410-2450.
