I know parisian pastries, but not sure how a good butter tart is suppose to be. All I can say is that the tart itself is pretty good here, but the filling inside makes ALL the difference. Tried a few and the best was definitely the pumpkin tart because it was not overtly sweet. The blueberry tart was slightly too sweet and the raisin tart was sugar OVERDOSE. It was covered in a sugary glaze (I think it was caramel), but it was so sweet that after one bite you already don't want to eat it. NOT good.
