Haven't had their food in a few years and made sure to make a trip when we were here in Vegas. Line went fast, and got longer as the afternoon progressed, but unfortunately there wasn't a lot of seating due to how busy they were.
Fries came out cold and onions were very hot. Burger meat was fresh and sauce was good.
Would not go out of my way to eat at tnhis location due to my experience, but would stop if I was in the area.
