The worst diet ice cream I've ever had. I've tried 3 flavors and they were all so bad I left them in the break room at work. I think pistachio was by far the worst and coffee was probably the best I tried. I have not tried birthday cake but I know a lot of people who like that particular flavor. The bonus is that it's got added protein and only has like 250 calories for the pint so it's really easy to work in and still hit macros. If you don't go into it expecting ice cream but rather a frozen treat, it'll probably hit the spot. I personally don't like it at all because it lacks the creaminess of real ice cream. Halo Top is to ice cream as grocery store cake is to a high end bakery dessert.
