I will tell you that the line for this is unbelievable all the time. HOWEVER, for a 24 hour taco shoppe in the heart of Las Vegas, what isn't a wait.
I came here with a group of seven around midnight on a Saturday. I grabbed a table outside and chatted with the security guard by the door. My friends proceeded to go in and wait in the 40 minute line which had been out the door since we arrived.
40 minutes later and a lot of dead bugs on the table in front of me from the fluorescent bulbs above, the food was served hot and ready. Just from tasting their salsa selection was fresh and delicious, giving its own spice to the flavor. I got two tacos for a decent price and carne asada fries. Overall the food was incredible!
There are a lot of make believe Mexican food joints scattered through our Vegas however this one represents and is delicious. The food was great with their own spices and peppers to the mix, truly a traditional Mexican style of cooking.
Sadly I dock one star for the ridiculousness of the wait and one for the cleanliness of the lobby and outdoor seating. Good place to visit, not so much to stop.
