Not sure why I haven't noted this before, but they take all their orders by hand (sans computer) so don't expect to order quickly. Prices are slightly higher than their competition, but not by too much.
That said, the staff is always very nice and helpful.
I can confirm that their Chicago deep dish pizza is excellent and authentic. Break out your forks for this one. Wings are pretty good but the spicy bbq sauce is anything but that. Maybe they gave us the wrong sauce? Not that big of a deal. Their regular crust pizza is fairly good as well.
As always, if you are paying by card you have to tell them when you place the order. Yes, they ask if you want to tip the driver ahead of time.
