i live in the Los Angeles area and i was wondering if you guys know of any restaurants with working magicians in LA other than the magic castle? I'd like to start dong restaurant magic someday but i want to see a professional at work so i can start getting ideas about what works and what doesn't work.

Check with your local magic club, they can give you better advice in person than we could online.

go to that magic castle or whatever and watch

Yep, you can go to the Magic Castle all the time from South Dakota can't you. It's a heck of a walk to Los Angeles. BTW Learn capitalization rules and grammar
