As friends sup quietly in a private banquet hall, chaos reigns a floor below. There, stones hurtle toward the wall, forming piles of rubble soon swept away and forgotten in the clamor. Still, the friends dine peacefully, unaware of the destruction happening under their feet. At the two-story Irvine Lanes, bowlers topple pins on the first floor's 40 lanes while the second floor hosts private parties and catered events in an elegant setting. Of course, a snack bar lets bowlers eat downstairs, too, and a full arcade, bar, and smoking patio keep outings interesting as the machine whittles new pins between frames.
