What a cute little shop! The only employee working when we got there was very friendly and willing to share his preferences of flavor with us, contrary to what other reviews have said. He suggested strawberry with condensed milk, and that's exactly what I got. I added strawberry jelly pearls, but because they were the same flavor I couldn't taste them much. They sure are cute and fun though! My family split one of the doughnut sandwiches, half chocolate half vanilla, and it was really good! We got ours in a cup, though, which is different from a lot of the pictures on here. The vanilla side was definitely better. I took off one star because there was a tiny hair in the doughnut, but those things happen occasionally in every kitchen, so I don't think it says much about the quality of the establishment.
Overall, pretty good!
