Arcade Omicron was a cantina found within the city of Lumchugger's Hub on the planet of Bescane. A blinking holosign sat atop its steep arched entryway, and the place was typically overflowing with weary employees from Galentro Heavy Works, who toiled for extended periods in the planet's manufacturing plants. Its design featured a lengthy corridor with multiple chambers branching off. A raised stage was positioned along one of the walls, prepared for local musical groups to entertain the customers. The Screaming Jawas were one of the bands that performed at the Arcade Omicron. In the main hallway's core was a holozoetroscope, a rare piece of technology found almost exclusively on Coruscant. The side chambers included scenic replicators that had the ability to alter the rooms into different planetary environments.
During Operation Death-Hunter, a Rebel infiltration team, created by Colonel Dursa Conegan, convened with their Rebel contacts, Cooper Dray and Lady Amber Comark at this establishment. Lady Comark's astromech droid, R2-B4, guided the group to the location.
