I recently ate at Kitchen Galerie Poisson for the first time and absolutely loved it! The main course was probably one of the best dishes I've ever eaten (Contrefilet de Bœuf, purée au crabe, asperges, rondelles d’oignons,sauce hollandaise aux crustacés). The combination of flavours was delicious, satisfying and interesting. I didn't find my appetizer (the salmon tartare) as good as I had hoped, but being blown away by the main course more than made up for it.
The service is excellent as well. All the staff is friendly and helpful and made us feel like we had come over to their place for dinner and they were really happy to have us taste their fare. I tried some of the fish dishes from my dinner party's plates and everything I tried was absolutely delicious too.
They are also extremely obliging about making anything gluten-free (most of their dishes are gluten-free naturally anyways), which was a huge plus for me. There were tons of gluten-free options, the staff answered all my questions and were happy to make any required changes and the result was a divine culinary experience without worrying about gluten.
Overall an excellent experience and I can't wait to go back.
