On the first visit, I made the mistake of ordering the mixed softserve because you can't really taste the sweet potato softserve properly.
Purple sweet potato with purple potato paste:
This time I just got sweet potato softserve with some extra sweet potato mash.
It was much nicer and the whole thing was not sweet which was great, the mash made it even more delicious because it was like having real sweet potatoes with icecream.
The bill: $36
