This is authentic Mexican fast food. It's not Taco Bell, it's not Chipotle, it's not Laredo's or El Pastor or La Hacienda. If you want sit down Mexican food go elsewhere, if you want fully Americanized Mexican food (i.e. lots of cheese) go elsewhere. If you want a lot of grease surrounded by actual Mexicans also eating a lot of grease come here.
$0.99 ground beef tacos (again, no cheese unless you add it) and the Carne Asada are the best ways to spend your money here. The burritos are huge and greasy.
They are open late, everything is prepared fresh, and the prices are ok to great depending. Definitely one of my late night go-tos.
