The chuckbox...wow. The burgers were phenomenal, the fries were good but not amazing, the condiment bar was scary but I did have the cajones to put mayo on my burger and I walked away with narry a hint of a problem. I won't make a trip to Tempe for it but if I'm around campus and wanting a burger, this is where I'm going.
btw - the cash only thing, annoying but not a deal breaker. I wish I was the owner of that ATM machine.
