My husband and I are on the cusp of having lived in Las Vegas for 4 years. We moved here from LA near the 10 and 110. Basically, we know our tacos.
We've had good tacos in Las Vegas, but none ever compared to the street tacos from a stand or truck somewhere near an LA freeway.
This all said, I took my husband here for lunch about a month ago after months of insisting it was worthy of his consideration. He's gone back several times since, declaring their tacos the best in Las Vegas. I've been along for a few.
The carne asada taco is available for $.99/ea on Wednesdays. All of the meats are well prepared. The pastor is sweet and charred. The barbacoa is moist and tender. The chorizo is flavorful and just the right amount of sweet. The asada is beefy and crisp. The lengua is tasty. Carnitas will be added to the "one of each" taco order.
The salsas are literal and figurative FIRE. If you like your nose to run while eating (which I do), load up on the salsas.
The interior consists of 3 - 4 four-tops, a counter for ordering, one large trash can, and a large flat-screen TV above the salsa bar. The storefront is next to a gas station. It's not a place for a large party sit down. In fact, most guests order the food to go.
