Ann Arbor being a college town, it naturally had a wide variety of pizza places. My favorite place -- and indeed my favorite restaurant of any kind in the nation -- was Pizzeria Uno, the deep-dish pizza place that originated on the corner of Wabash and Ohio in Chicago. To this day, I'm still trying to get to as many Uno's restaurants nationally as I can. However, the Ann Arbor Uno's, located on South University, went out of business in the mid-90s. It was the site of many grad student gatherings (birthdays, dissertation defense celebrations, etc.) during my years at UM. When not with a group, I made a weekly take-out order from Uno's.
