The Ballroom was a bar located at Third and Water streets near the bad part of town. The study group went there to celebrate Troy's twenty-first birthday during their second year at school. Jeff described it as a divey establishment with an ironically fancy name. The bar was a familiar place to not only him and Britta but also Shirley who frequented the bar before going to Greendale. Its only appearance was in the Season Two episode "Mixology Certification".
The Ballroom had a small entryway where the Ballroom bouncer would check ID cards. The layout of the establishment includes several tables, booths and the main bar with stools. The atmosphere of the bar is lit very low, with the walls decorated with Polaroids of repeat customers. Along with pool tables, The Ballroom has classic arcade games including "Asteroids" and "Centipede".
