Unsung Mexican food in north Sunset Park
If you like holes in the wall that serve up great tacos, tortas, and cemitas with traditional meats, you have to check out Carmelita Deli at 780 4th Ave between 26th and 27th on the west side of the avenue. It looks like a regular deli, and you walk to the back, and they have a tiny kitchen -- there's more room in a taco truck -- in which they somehow manage to have multiple people cooking.
The food is terrific and cheap, and sinfully good. Everything is cooked on a round griddle, the middle of which is raised up so all the fat drains into the outer ring. Everything good is cooked in that fat at some point. Two touches that I really like are the grilled cebollitas that come with everything, and the fantastic, free condiment bar. The salsa rojo is nice and smoky, the verde has chunks of avocado, and the guacamole is great. There's also radishes, pickled jalapenos, and lime wedges.
Note also that the $1.50 tacos are the snack-sized kind with two tortillas, a bit of meat, and a sprinkle of onion/cilantro. Here's another accurate review: http://11870.com/pro/carmelita-deli
I second this recommendation. I stumbled upon this place because I was getting my car serviced nearby, and I had a very tasty chorizo torta. There were a few other folks squeezed into the space in back, eating, so perhaps locals agree. I think future appointments at the garage will be good for checking out the rest of the menu.
