This location is okay, but I admit I enjoy the Green Valley Ranch location better. Ifind they make the burgers way way way too salty, but on the upside they will chargrill your burger if you ask, which I always do. I like the flavor of the char on the burger when it gets grilled in that manner than on the fryer they use normally.
Honestly, if you're in Red Rock Casino and you want a burger, you should be going to LBS instead of here, it is miles better.
