Whenever I need some good fast Mexican food I go here. Apart from it being close to my house, they have some pretty good food. I've never really been inside the place. I usually go through the drive through and there's usually never a line. I think I've only waited the most 2-3 mins to get my food.
Service is usually friendly and speedy. Staff could probably smile a little more but it's not a big deal. I usually order their street tacos, tostadas, taqueria, tamales or their veggies burritos. The fact that they even have a vegetarian option on their menu is awesome!
Another thing I'm quite happy about is that they open pretty late. Maybe not 24 hrs, but late enough. If you haven't already give this place a try. They have a long menu with lots of options to choose from.
