4 California venues work as an adults' evening out rather than a children's party destination — late sessions, a bar or lounge, and racing that stands on its own. They're spread across 3 metro areas, so most of the state is within a reasonable drive of one.
Check session times before planning around one: evening availability is the thing that varies most, and some venues restrict late slots to leagues or private bookings.
