It depends on the size of your business place. If the total area is 111, the dining area will account for more than 61-71, the kitchen will account for about 21, and the cashier and waiting area will be together. The toilet doesn't need much space. For example, my small restaurant will allocate 1.71 square meters, which is similar to the above ratio. I suggest going to someone else's restaurant! ! !
