An offshoot of a popular, London-based entertainment concept, AceBounce opened a Chicago outpost in June. The downtown venue hosts team-building events, parties, conferences, and product launches. It has a 1,915-square-foot private room called the Parlor, which can host receptions for 100 guests. Illuminated with UV artwork, the space has three ping-pong tables, its own cocktail bar, and wireless presentation equipment with an L.C.D. screen. There are also two semiprivate rooms: The 560-square-foot Gallery area has two ping-pong tables, and can hold receptions for 50 guests, while the 554-square-foot Garage has one ping-pong table and space for 25 for receptions. The main space is 3,725 square feet, and can hold classroom-style seating for 111 or theater-style seating for 150.
