Newark definitely has some options. Might not be exactly what OP asked for but interestingly enough there’s a Mexican - Ghanaian fusion food truck called Afro Taco in Newark that’s pretty good.

I’m not Puerto Rican but I taught in a Puerto Rican neighborhood and the school down the block from mine was named after LMM. My school was named after the musician Rafael Hernandez and another down the street was named after Roberto Clemente. So I’d say with LMM being in that company, he’s pretty well known and highly regarded.
