At Michael Mina in San Francisco, it's hard to miss the giant flip board modeled after arrivals and departures signage in train station waiting areas. In this implementation, the concept communicates last call wines from the expansive list. Once a guest purchases the bottle, the sign repopulates with another selection from the one-bottle-remains cellar.  

We love the entertainment value and interaction. If it wasn't in a fine dining restaurant, the scheme would seem like a game show but the luxury atmosphere and the fact that many wines cannot be found in a bottle shop make this experiential element invigorating.
