Studio City Kids
11118 Ventura Blvd., Studio City
Though it admittedly rarely rains in LA, this indoor playground still beckons. There's a big slide, ball pit, light-up floor, and more. The best part, though, is that the grown-ups can sip coffee at the cappuccino bar while the kids play. However, even adults have to remove their shoes, so if you'd like to join your kids in the bouncy castle, go right ahead.
