This pizza is amazing. I cannot speak for the authenticity and all of that, but good pizza is good pizza. The deep dish is what you need to get. I can't even eat a small in one sitting and I am a pretty big eater.
The inside of the place is a dive. You can eat in but it's got the feel of a take out place mostly, for instance, you have to get your soda at a pop machine inside. But yeah, the pizza is quite phenomenal. If you get the deep dish. DOWN SIZE. It will fill you up fast.
