Thanks to Go Dairy Free viewer Tara for emailing this recommendation.
If you go to the website, this may appear like just a supplement shop, but Healeo offers much more. They offer vegan food, superfood drinks, and hemp-based dairy-free soft serve ice cream! I know where I'm going on my next trip to Seattle.
Here's a (very loud) YouTube video of their soft serve – http://www.youtube.com/watch?v=qTV9DMxQz1E
