A couple weekends ago I went to Dessance with some friends. This is an all-dessert restaurant. Yes dessert only. The chef is Christophe Boucher (ex chef patissier of Ledoyen and Grand Vefour). Dessance opened somewhere in the beginning of this year.
The restaurant offers a menu carte blanche which consists of a mise en bouche, and 4 desserts of chef’s choice. We took the opportunity to share this experience by ordering the menu for two. They also offer a drink/wine pairing. (we did not try)
In the picture on top, you see the mise en bouche. I didn’t fully understand the French to know what was in there (and if I would, I would not have remembered anyway). From what I remember, it had pear and wasabi. It tasted fresh and I liked it.
Below is the first dessert we had. Honestly don’t know anymore.
Sorry bad bad picture. Don’t have a better one 
I believe this was pear with greek yoghurt ice cream and some other things.. xD
This here was a beetroot dessert. With white chocolate cream, cranberry compote and a sorbet. This one is memorable. This dessert was not very sweet and was balanced out with savory beet flavor and sour cranberry compote.
Omelette Norvegienne. My friend who didn’t take the set menu ordered this one as a single dessert. She kind of expected an omelette lol. It’s like a baked alaska. This one had a strong whisky flavor. In the center there was vanilla ice cream, caramel and a biscuit soaked in whisky.
After the desserts we had some mignardises which were a spoon with cream and some coulis, a marshmallow and a sesame tuille.
I’m sorry I don’t have accurate descriptions or high quality photos. I enjoyed the food and recommend this place.
