I'm surprised to see so many 1 star reviews for this place. I've probably ordered from them well over a dozen times and never really had a problem with the customer service or delivery.
I pretty much always order a supreme pizza whenever I call. In terms of delivery pizza, I don't think it gets much better than Guys, at least not for us on the near-west side. The crust is above average, I don't care what anyone says. But it's the cheese blend and toppings where Guys really excels. Everything tastes crisp, fresh and delicious.
I only have two complaints: they do tend to do a poor job of cutting slices and sometimes on the weekends they undercook pizzas in an attempt to get them out faster.
