Eh..not too awesome.
The tart flavor was AWFUL! Way too tart and the texture was grainy and strange. Everything else (sweet coconut, taro, cake batter) tasted like a slight variation of the other. Very one-note. The only flavor that stood out as great was the cookies 'n cream. That was EXCELLENT and possibly better than any Menchie's flavor.
The inside was sterile and depressing. After being at Menchies, where they practically vomit smiles, winks, and good wishes, Yogurt Vi seemed like a very unfriendly place -- even though the people working there weren't. The other reason Menchie's is better is because they have twice as many choices.
That's about all that needs to be said, I guess!
