"I tried one of the bubble teas at this restaurant, all of which are labeled as vegan on the menu. They were quite flavorful and the server kindly gave me samples of their new flavor and different types of bubbles. However, I found out that the milkshakes are not actually vegan, despite what is stated on the menu. It turns out that there is a milk-derived protein in the creamer used in the milkshakes."
