Old Chicago has the best loyalty program around. I love the World Beer Tour!
As a member of the World Beer Tour, I'm always getting free money put on my card. It's not the weak 20% off or buy one get one free deals- they literally add $6 to your card for random events. For my birthday, I got a free large medium pizza - a $17 value!
The food is good. I'm honestly not a huge pizza fan or critic, but I think it's a decent pizza. They have a huge selection of beer. An excellent happy hour.. Etc.
This is a great place to be a regular at!
