Shop-it-yourself Restaurants!

What do you think of a new type of restaurant where the customers bring the ingredients for the meal and the chef cooks it for them? I'm thinking the idea will appeal to people who enjoy shopping for groceries and food but don't want to spend time cooking after. A good idea would be to have the restaurant conveniently located close to food markets. Nothing is charged for the meal and profit is made from monthly/annual membership fees. It's obviously a members-only restaurant. The menu is advertised online offering details on the ingredients/quantities so that customers know what to bring with them and book a table in advance. What's your opinion? Can such business do well?
