Coming from a 24 Hour Town (Las Vegas) to the 'burbs of PHX, one of the things I miss is the plethora of late night and all night dining options.
Gus's is close to ASU, which I'm sure gives them a built in crowd of hungry students to support their 24/7 operation. We were looking for something late night, and this popped up on Yelp, so we phoned in a white pie, well done.
By the time we arrived, the pie was ready as promised, and they were jumping with orders and customers. Apparently they also deliver beer!
The pizza was AOk, could have used some more ricotta IMO, but it was good enough. We would pick up from them in the future.
