The Magic Castle is a social club for magicians that was built into the side of the Hollywood Hills. The building itself is a bit of a magic trick, in that from the outside it looks like a small chalet, but once you get inside, it’s a massive social space with bars, theaters, and a steakhouse. Getting inside can be…tricky? (Feel free to burn this book now.) You actually need to be invited by a member, and in order to be a member, you have to be a magician.
