The sporting lounge is a recurring location in Rise of the Teenage Mutant Ninja Turtles. It is an opulent sports bar and event room in the secret Yōkai section of Big Mama's Grand Nexus Hotel in New York City, catering to wealthy Yōkai clientele who can watch fighting matches taking place at the Battle Nexus down in the Hidden City, which are remotely broadcast to large viewing orbs in the lounge. The sporting lounge first appears in the episode "Bug Busters" along with the hotel itself.
The sporting lounge is dramatically wrecked in the episode "Battle Nexus: New York" when the fight between the Shadow Fiend and Baron Draxum tears upwards through the floors of the hotel itself before bursting through the lounge's floor to the terror of its patrons. The lounge is destroyed altogether by the Foot Clan along with the rest of the hotel at the end of the episode.
