It's going to be VERY HARD without a consistent menu. I've known
  people with restaurants who had constantly-changing menus and
  people like consistency. They usually fold in a few years if
  they don't settle on some standards. But... I REALLY wish them
  luck. I think it's a marvelous idea - and because *I* like
  surprises, I'd go there if one shows up in Naples, FL. == But
  many people want consistency. I think they'll do fine. I'm just
  saying that it can be hard to run a business that offers
  constant change and unexpected items. The clientelle will be
  limited to people who enjoy variety, creativity and a good deal.
  Mind you, that's a LOT of people. That's why I think they'll do
  better than restaurants that offer changing menus. I'm sure you
  can see how restaurants menus and a supermarket options are
  functionally similar? The only difference is who is cooking and
  the diverseness of items being purchased. Restaurant you order a
  few things. Supermarket you "order" (pick) a variety of things.
  But food's food. smile emoticon ==
