Fred Takes Betty to Dinner at a Very Expensive and Exclusive

Fred takes Betty to dinner at a very expensive and exclusive restaurant. The menu does not mention the prices. The server takes their order and both Fred and Betty enjoyed the meal immensely. When the bill comes, Fred refuses to pay because the menu had no prices and because he and the server never engaged in language indicating an offer and acceptance. The server said, "Are you ready to order" and when Fred said "yes", the server merely asked, "What may I get you tonight"?
