In n' Out Burgers and Baja Fresh Mexican Grills are fast food joints that are common throughout southern california. Might be great for non-Californian visitors, but I certainly won't travel all the way to sin city to frequent fast food joints that are right in the nick of my backyard.

Circus Circus on the other hand has some of the worst buffet in all of Vegas. But as the title of this thread has indicated, you get what you paid for.
