In our comparison of remarkable downtown Frozen Yogurt stores, YummyYo in the 360 building was still pretty new and somehow flew beneath our radar when scouting out Froyo places.
I had the chance to swing by YummyYo a few weeks ago and it’s very solid. Their original tart flavor is probably a bit better than Yogurt Spot and their green tea flavor is excellent as well. I would rank them both as 2nd in taste behind Mamboberry. I also got to try their cookies and cream flavor which was surprisingly excellent (not chemical-y tasting like some of the other yogurt places around town).
