Rebound
From Halopedia, the Halo wiki
Rebound was a bar in the Greater Chicago Industrial Zone, Illinois [1]. It's where Staff Sergeant Avery J. Johnson may have drank after learning of his Aunt Marcille's death. The bar had several bouncers armed with umbler stun devises. Rebound also had many dancers equipped with daimond shaped devises in their navals that read the credit cards of bar participants.
