Great steakhouse design. It has a wikipedia page - not that I should be surprised anymore, I guess.

When the Blackhawk stopped featuring orchestras in 1952 and removed the bandstand and the dance floor, Don Roth declared the restaurant's theme was "The Food's the Show" and focused on the house specialty of prime rib served from carts brought to the tables and its "spinning salad bowl."[3] Waiters would bring a large bowl of greens set into a larger bowl of ice. As they spun it, the waiters would add ingredients and describe what they were doing to the diners. Roth borrowed these concepts from Lawry's in Beverly Hills, California.

The Blackhawk remained open until August 31, 1984.
