Sweet Ritual is a vegan ice cream shop in Austin. Their soft serve is made from soymilk, coconut milk, sugar and natural flavors.
When I stopped by a few weeks ago, they had a special Nutter Butter Sundae. Peanut butter chocolate soft serve, homemade chocolate and peanut butter sauces, peanuts and chocolate chips, topped with a Nutter Butter cookie. It was incredible. It's a large portion too, I couldn't finish even half. Their shakes sound pretty awesome too!
If you're looking for something a bit healthier, you can grab a freshly made juice from Daily Juice. They share the same space.
You can choose from their extensive list of juices and smoothies or create your own. The Pineapple Popeye would be my first choice.
You can also visit Juiceland's two locations in Austin for amazing fresh fruit and vegetable juices. As I understand it, Juiceland and Daily Juice were one and then split off into two. Both menus look incredible.
