Tangeman University Center (TUC), UC's student union, is located in the center of University of Cincinnati's main campus. It is the home to Catskeller, the Cinema, the Food Court, UC Bookstore, MainStreet Express Mart, MainStreet Connection Center, Mick & Mack's, Quick Mick's Cafe and PNC Bank as well as many meeting spaces and study areas.
TUC was reconstructed in 2005 with the original clock tower placed atop the skylight in the 90-foot atrium.
