I'm only able to review this because I went to another Yogurty's location, and the taste was so much better.
The first time I had come for froyo in a really long time, I came to this location in the evening before closing. There have a variety of flavours but seemed like only a few machines actually worked. Of the flavour that I actually was able to pull out, I felt like it tasted watery and icy and a little sour. I thought that's just how frozen yogurt tasted like, compared with say, soft served ice cream.
I went to another location recently, and it was very different. In addition to a smoothly working machine, the taste was creamy and not sour, and compares with soft serve ice cream texture. So much better.
I wouldn't come to this location again. It was also way too crowded.
They do have bubble tea on premises as well. It wasn't amazing.
