There's nothing like the original. This is the first Pizzeria Uno and isn't anywhere close to the same as the chain. You'll need to get there during an off-time or be prepared to wait.
It takes about 45 minutes to make the pizza, so you order before you take your seat. Get a salad if you're hungry, but make sure you save room for the pizza--the deep dish sausage was fantastic.
If Uno's line is too long, try Due's down the street. It's exactly the same menu/food.
