Lou's deep dish is great, as is the company. They go to the big church in the burbs I used to attend and basically donate hundreds if pizza each year for free for all kinds of meetings and such. They also operate locations in underesourced areas of the city and use it as a way to help young people get job skills for the future while contributing to the community.

As Hal and Winky mentioned above, go get a thin crust at Piece Brewery in Wicker Park/Bucktown. Nothing comes close to it anywhere. It's magical good.
