One of the best!
Small little place but I have never had to wait longer than 5 minutes to get a seat. This place is a gem in the valley. The servers have always been friendly and fast. I've never had a problem with them in the 15 times I've eaten there.
The food is great and traditional, except for the shrimp burrito. The shrimp burrito is the best I've ever eaten. Get it enchilada style (they put a garlic sour cream sauce on top with some more shrimp). The carne asada is very tender and cooked perfectly and their taco salad is very good too. I love the shrimp cocktail. Margaritas are to die for. The salsa with the chips isn't chunky so I recommend asking for pico de gallo when they take your drink order.
This place is a must for any fan of mexican food. Prices are cheap too, in the $6 - 10 range.
