I came here specifically for the vegan soft serve. I've been wanting some but it's hard to find!
The vegan flavour is mint. The taste is not as sweet as typical soft serve, and the consistency is a little more whipped vs typical liquidy soft serve. This bodes well if you're having a dipped cone since it won't drip that quickly.
I love that they have the offering, but I'm still looking for the perfect vegan cone.
