Being from Chicago, and having ate deep dish pizzas at Lou's back home I can honestly say this is spot on! Expect your pizza to take 45min-1 hour to make. Don't complain about how long it makes, use that time to oh I don't know... socialize with who you came with and get off your phone? If you're going to be spending that much money might as well enjoy the ambience you're in, instead of complaining.
Outdoor seating, they have misters on for when it's really hot, they have a fireplace outside as well, for when it's too cold. Also, indoor seating. I have gone here 5 times since they opened, even though they're 45min from me I will still drive out there for my pizza. Try calling your order in before you get to the restaurant, so it starts cooking! Then your wait time won't be so long. Doesn't anyone use their brains anymore? Ha! Enjoy folks!
