I have had pizza to go numerous times, have eaten other food in the restaurant once.
First, things first... the Chicago-Style pizza is always amazing. Have tried a few, but the vegetarian is my favorite.
Now, the only negative: The service is strange, sometimes the pizza isn't ready for another 10-20 minutes after the initial estimate. Also, the employees can be heard arguing with each other in the back (usually when a pizza isn't ready on time).
Overall, this place is great and I will go back again and again.
