I guess I'll go 5 stars on this one. I found parking right in the lot that it is located. I got there on the later side (10pmish?) and they were in full swing. I ordered 5 tacos. I think I just got carne asada and pastor, but everything I had was good. The tacos were not tiny and were filled nicely. I added some condiments on them from the condiment bar. $1.50 a piece. They ran out of nopales at the condiment bar, but I'm willing to overlook that as I was not anticipating them to begin with even though they would have been a nice touch.
There are chairs set up outside of the truck for you to eat on. There are also a few stools on the truck, but those were occupied.
This was exactly what I was looking for on the late night off the strip. I know that isn't late for vegas, but it was a week night and I had been all busy all day and night previously.
I would return for sure. I'm glad I found this place on yelp.
