Back in the 1950s, New York City saw a new food service option: the automat. Menu items were prepared and put in individual displays. Customers used coins to pay, and unlock the door to take their food item(s). Automats had tables to sit at to eat. Basically, it's a restaurant without wait staff. You've decided that this idea could make a lot of sense in a world where Covid continues as a replacement for a food court in a mall. Using the Blue Ocean approach, put together your approach to bring this cheap and friendly way to eat into the market and be profitable as you do.
