The Chuck Box is one of the best burgers you will find in the Phoenix metro.
The style is kick back, with wood chips on the floor and a pick-up counter, so you can never feel "too scrubby" to go to the Chuck Box. And the condiment bar is top notch, which is always major points for me. If anyone has been to the Original Hamburger Works near downtown, they know what I'm talking about, and this one is comparable.
Fantastic hangover food and really good the rest of the time.
