You don't come for the food. A simple but fair statement, Onoir is a dining experience and definitely worth a try. I feel like it is all well done with the choice of food made before with a simple but broad menu featuring surprise options for each course.
I have been twice as its close to my home and a great option to bring visitors too. The first visit was so disconcerting I had to take a toilet break to see something - freaked ha. You just don't adapt to it.
Our food experiences were good but to elaborate on my opening comment it is never going to be about the food. Logic would dicate an experience orientated restaurant like this needs to keep it simple and appeal to a broad range. I read one reviewer complain about having to eat with their hands. . . You are provided with a knife and fork so you don't "have" to do anything. But yes I tucked in with my hands to make sure I got every last bite and worth giving a try :)
