Circus is the upstairs part of the Cavern Club. It features circus themed decorations including a 'big top' tent over the bar. The bar includes free pool nightly, and karaoke Monday, Wednesday, and Thursday with Double Take. Typically on other nights, there's a movie playing projected onto the stage area.

Circus generally consists of fewer college students and more Ann Arborites except on Thursdays (the typical 'bar night' for students).

[edit] Drink Specials

During the summer, Circus is known for $.55 Pabst Blue Ribbin cans. During the school months, it raises up to $1.25. They always have $2.00 Long Islands, and generally one shooter special.
