Smoothies are a great product to increase revenue, no matter what type of restaurant, cafe or store you operate. Since they're are so many different ways to make smoothies and so many different ingredients you can use within them, the possibilities are almost endless. Typically, smoothies are made from any combination of dairy, frozen water or ice and fruit or some type of fruit flavoring.
By adding soft serve ice cream to the smoothie you get the dairy aspect and the frozen aspect. This combination is actually better then ice/shaved ice solution because it makes an extremely smooth smoothie. There's nothing smooth about crushed or shaved ice. With the addition of other ingredients you can really cater to a niche crowd as well. Add some protein powder and energy blasters to your smoothies and you'll be the go-to cafe for people on the go. What's more, by adding these simple and additional ingredients you can set a higher prices for your smoothies.
Cafe's are an obvious choice for smoothie production but any other type of food establishment can offer it as well such as: ice cream shops, cafeterias, restaurants, colleges/universities, stadium & entertainment venues and kiosk stands. The important thing to remember is that it usually costs less than $2 to make a smoothie but generally any smoothie shop can charge between $6 - $8 for one smoothie per customer. So, if you are able to offer some recipe driven smoothies your cafe or shop can fare quite well.
