Been here a few times to date and it has yet to disappoint. Granted the tacos aren't as cheap as the ones in LA, the portions are bigger with loaded guacamole on top. You can also get the grilled peppers on the side for free, which is nice.
I normally stick with asada, lengua, and cabeza tacos, but last time they were out of lengua at 430am. Their Asada fries are pretty delicious as well. The best part about this place is probably the unlimited horchata and orange bang fountain drinks.. So good!
The place gets pretty packed in the wee hours after everyone leaves the club. It's within walking distance of Wynn/encore, so if you go to any of the clubs there, go to gordos after!
