There are advantages to offering self-serve custard as opposed to operating full-service stores. Obviously, you will need fewer employees as the customers do most of the work. Happy kids and families will make their own frozen concoctions.
The typical self-serve ice cream shop can offer more flavors to the customers, typically six to ten different flavors; however, many machines are needed to accommodate the desired flavor offerings.
Customers see these stores as a destination more than an impulse buy. They know this will be an experience that they will do for fun more than just a dessert treat. Self-serve custard stores offer not only a variety of flavors but also a variety of toppings.
