Absolutely stunning environment, definitely unique and different.
Tried about 5 sweets (went with a group of people). Taste wise everything was OK. I'd say they were all about 4/10. The pastries are quite small too, for the price you're paying. The tart especially is very dry. The food is overpriced for how is tastes.
Overall, I think its the environment you'd enjoy more than what you actually would order. Never go here hungry, you won't be satisfied.
I would recommend this place, if its nearby, if you want to just grab a coffee or tea with a friend, and chat in a pretty environment. Besides that, nothing worthy, unfortunately.
