I couldn't sleep and clicked on a random new release on HBO. I was interested by the function of the restaurant and wondered why there isn't more of this vending machine restaurant now. Then it became enduring watching a series of legends speak fondly about this restaurant in its hay day. Colin Powell to RBG were interviewed. They could have took the turn into racism and hate as so many shows do nowadays. I was relieved to see they didn't. It was mentioned, but not overdone. I'm curious about the producer and director considering the high profile people in the doc. I look forward to a savvy business person trying this type of restaurant again.
