The Retail Plaza boasts several restaurants including Brown Bag, Downtown Deli, Best Bagel and Prime Time Hotdogs. The building was originally built as office space for the United American Bank, which was the cornerstone of the banking empire of Jake Butcher. After the FDIC raided Butcher's banks in November 1982, United American collapsed, and Butcher was eventually convicted of bank fraud. In 1983, the Plaza Tower was sold to Chicago-based real estate investment firm JMB Realty for $28.5 million. First Tennessee moved into the building in February of the same year. In 1994, JMB merged with Heitman Properties, and Heitman assumed management of the Plaza.
