Didn't see the name posted anywhere on the vehicle, but the address is correct and the pictures look like the right truck: parked right between the convenience store and Luv It's walk-up window is this business.
Menu is written on the windows, serving up fresh-made Mexican classics like $5.50 burritos, three-packs of tacos, and every tasty meat you crave when you think of the barrio. The quesadilla is a bit pricey at $6 for 4 pieces, opted for lengua and it wasn't as plentiful as I'd like for the price but what was there was tender and tasty. The green salsa is my favorite of the available options.
Service was friendly, food was made fresh and quick, and I'd keep it in mind if I'm in the area late at night- didn't see hours posted but they appeared to just be getting started when I swung by around 8:30PM.
