This is one of those places I just don't get. Attached to a full service car wash/gas station and a convenience store this place is always hopping with folks getting food to go. I have tried this location about a dozen times in the 10 years we lived in Vegas and it was always just decent, every other time. Remember I said decent not good.
The food is always prepared overly salty, never the same portion any time you order it and every fourth time they give you the wrong to go order. Note that I don't order anything fancy here as nothing is fancy, I just order one of the beef taco combo plates.
There is no consistency with the food proportions and the way it's cooked. Sometimes the tacos are out of this world and served hot and sometimes the food is cold by the time I drive 5 minutes down the road and the beans taste old and they've salted my beef taco to death. In the second scenario I just end up throwing it in the trash after two bites.
Perhaps the secret to this place is to either be so drunk you don't notice how bad the food is or to take your to go order and sit down in one of the dirty, never bussed, communal round tables so you can scarf it down as your car gets washed or your gas gets pumped, that way the taste of the overly salty food just passes quickly through your taste buds. One more thing, this place employs the grumpiest, most un-friendly counter staff. Try smiling at them when you're paying and tipping 20% and all you get is a grumpy look or a scowl. Advice lighten up guys you're supposed to want customers to return.
If you want real authentic Mexican food in a clean place where people preparing your food not only prepare it with love and give you service with a smile, head to Pepe's. You'll be better off and be glad you didn't spend $9.95 on a taco plate.
