There is a famous ice cream shop in Cochrane, Alberta, about 20 minutes from the city of Calgary, called MacKay’s Ice Cream (https://www.mackaysicecream.com/). They opened in the early 1950s and are an icon drawing about 5,000 visitors on a nice day. Years ago I lived in Cochrane and was the president of the Chamber of Commerce. At that time, we developed the economic development plan around the tourists that MacKay’s Ice Cream attracted to the community.
There are some excellent ice cream shop examples from coast to coast. I hope they can be sources of ideas for your shop.
