I don't understand some of the hate....it's a lunch buffet for under $10.
You eat a couple burgers,a few pieces of fried chicken and you are ahead.
I don't usually eat Mexican food outside of Taco Bell but seeing how the majority of the staff seemed Hispanic,there's a good chance that this is some authentic dishes.
Grab a few ice cream cones for the way out.
I'm not saying the food was awesome but I'd easily rank it over the buffets at the Luxor and Excalibur.
