Amazing. Most of the toppings are GF and the texture and light taste of the soft serve fruit is perfect.
The servers were very friendly and made sure that they get all ingredients for my smoothie from the back. They do have waffle cones and pretzels on site but are careful. However, I did feel sick after having piña colada. I don't take artificial sweeteners that well, but it definitely felt like something I am intolerant to. Not sure if it was contaminated.
Soft Serve Fruit is made of just three ingredients: fruit, water and a touch of organic cane sugar. It's insanely delicious, and is an awesome snack or healthy dessert. I'm currently addicted. Almost all of their toppings are gluten free, and they are super careful as well as caring about the gluten-free community.
