I had the small lemon pie flavoured drinkable dessert. It tastes really good, almost like you were really drinking a lemon pie. The consistency is really thick. The only downside is that it is super expensive: I took a small cup that was probaby half the size of a small cup at Starbucks and it cost me more than 5$, which is crazy expensive...
Probably won't be ordering the drinkable desserts again, but I will be trying their ice cream next time.
