Does your country have some sort of review website? here in the US, we have yelp, where customers talk about their experiences at restaurants, bakeries, etc.
I looked at their website. While it is impossible for me to rate this shop's flavors, I would say that the quality is somewhere in the middle of the pack, not the best but not the worst. I am a pastry chef. I have attended international competitions in pastry, and have seen world-class cakes. This bakery is missing many details. I don't like the hulls left on the strawberries. (nothing inedible should be served) The piping is sloppy, and much of the assembly isn't great. It's better than a supermarket cake, but, not a top tier item.
I am sorry, I cannot help you much more, welcome to eGullet and good luck to you!
