If you are in the mood for some delicious, authentic pizza, I would tell you to visit Giordano's Pizza. It is a great restaurant decorated with historical artifacts of the city. The food is simply amazing, and very filling. If you are going to Giordano's, make sure you are hungry! They're pizzas are huge and so worth the price, which is not even that expensive. They also serve much more than pizza, including pastas, salads, sandwiches and more. There can sometimes be a wait, so be sure to get there early before the rush! Giordano's is a definite MUST TRY when you are in Chicago!
