On weekend nights, Cal Bowl turns down the regular lights and turns up the black lights, making lanes glow neon for cosmic bowling. Meanwhile, players themselves supply the soundtrack as they take the mic on the karaoke stage. During the day, open bowling commences as usual, with players sending balls spinning down glossy lanes while fighting the urge to slide down after them. Between frames, guests escape to the 7,000-square-foot fun center, stocked with arcade and redemption games and four billiards tables.
