El Mezcal Restaurant

They don't cater parties per se but we get their food at work alot. You can buy large quantities of all the meats (chicken, beef, pork), also large quantities of queso and salsa. You might find out if you can buy large quantities of diced tomatoes, cut up lettuce and shredded cheese( or just do this part yourself), taco or tostado shells, tortillas - then you could set it up buffet style and let people create their own favorite

U do get free refills on drinks but they have Coke now instead of Pepsi I'm not sure on the other stuff but the food is awesome
