Just came upon this priceless ad from, I believe, 1974:
Anyone remember getting ice cream at the Crystal Palace? It wasn't on the 7th floor with the other restaurants, but on 3.
Come to think of it, I remember getting ice cream at the Oakbrook Center Field's store, in a place they called "Strawberry Fields," which had an all-strawberry theme: strawberry ice cream, strawberry-decorated cookies, chocolate-covered strawberries. It didn't last long, but I was enchanted with the idea, and the strawberry-printed tiles on the walls.
