They’re all plastic, there’s another place of his next to VanNuys airport thats kitted out like a WWI French farm house thats been hit by artillery.
It’s the 94th Aero Squadron. I ate there many years ago when I spent a lot of time in LA. Worth going to.
And if you fly up to Oxnard for lunch (we took a rented Cessna 182 from Van Nuys) the resturant at the airport was also aviation themed with lots of neat items. The salad bar used a T-33 canopy for its cover.
