Restaurant Menu Bingo
I have a new idea for a restaurant promotion game. The chef/restaurant owner chooses a certain combination from the menu - e.g. spinach soup + small Pepsi + fruit cake. You win the game by ordering exact this combination from the menu - the only problem is that you don't know what it is. The winner of the game takes the jackpot, which will be increased by a certain amount every day, until someone finally places the winning order (of course, the prize money has to be spent at the restaurant). Then, a new combination of orders is chosen (possibly at random) and a new round of the game starts.
Of course, the details would depend on the particular restaurant, e.g. if the order has to be placed in one and by the same person, or if it's enough that the people at the same table order the particular dishes during the course of a meal/evening.
Reward: Free food if I ever happen to visit the restaurant
