My 5 year old loved bowling for her birthday. We prefer an alley not far from LB in Garden Grove at the intersection of Valley View and Lampson. You may be successful calling them and making reservations. You may also consider going to Boomers! in Fountain Valley. My son celebrated his birthday there and we all loved it! We got unlimited wristbands which allowed us to play many rounds of mini-golf, bumper boats, rides, and more. We also played some video games, ate pizza, and had a blast! Both locations are open late. If you're up for daytime fun, I would consider going to Soak City at Knott's Berry Farm. It's a blast!
