I love this place! By far the best quick Mexican joint I've found west of the strip. Open late, sometimes 24 hours, and the food is really really good. They've got a bunch of different meats; lengua, etc, good carne asada fries, horchata and all that. People keep asking me and yes!! It's better than Roberto's. It's also at the end of my block, so I'm all in on this place.
I have to say that tacos el gordo is still my #1 taco stop in Vegas; but this place is a close second.
