Horrible. My wife and I just don't get it? We tried several flavors and hated it! I had the blueberry and not only was it a very weak flavor, but I thought it tasted like medicine. I also had the vanilla and wasn't impressed. Very dull flavor as well. My wife was also not impress with her choices. We just didn't get it? Maybe it's all the toppings masking it, or just convenience of the location that gets people in there?
