I was a Giordano's guy when I was growing up in Chicago, but Lou Malnati's may have just won me over. First off, if you go for lunch and get the lunch special deep dish pizza it's not going to be as good because they have them pre-made and ready to go for people who need a quick lunch on their lunch break. If you have the time order a fresh one, pay the extra dollar for the buttercrust(it's worth it) and get extra sauce if you're a "sauce guy" like I am. Add whatever toppings you want, I just keep it basic with pepperoni but you can't go wrong with anything. The apps are pretty good too, and I believe their ranch is made in house, delicious!
