I'd give this place a 3.5.
Came here on a Groupon deal with a friend of mine who's came before and was nervous from the dark experience, but was willing (sort of :P) to come with me again (thanks!). Totally my first time.
I had an alright time. I felt like my expectations were too high however so I will take some responsibility for what I expected and what I actually experienced. I thought the decor in the "foyer" area was interesting and it looked nice. The hostess and the servers were nice. I ordered a beer, the octopus appetizer, the shrimp risotto and a surprise dessert which you order beforehand (obviously). In we went into the darkness.
The dining room area felt small however it could just be that since our sight was out of commission that people normally speak more loudly and our ears are more sensitive but the sound in the room was very loud and people felt quite close to us. Feeling around the table we could find our napkin, small plate, fork/knife and a small butter. I'm not sure what it was but maybe since I was trying so hard to see things it put strain on my eyes and gave me a slight headache. It didn't go away until we left and temporarily went away when our food came which distracted me.
We were served with a glass of water and a small, fresh dinner roll shortly after, then came our beer and then finally our appetizers. Once I picked up my fork I already gave up and started to use my left hand to feel around for my food. My octopus were cut into small pieces and it felt like it was placed over a few leaves of arugula with a balsamic/olive oil vinaigrette. I thought it was quite tasty and had fun trying to find if I had any food left on my plate. After our plates were collected, it felt like forever waiting for our entrees. A bunch of tables surrounding out sounded like they had their entrees already even though we were one of the first tables to be seated that night. We figured it might have been because my friend ordered the fish which was fried very nicely and it was hot however my food was left a bit cold unfortunately. Not only were my shrimp cold but my risotto didn't really have the same creamy texture I was expecting out of it. I was a little disappointed in that but my shrimp were big and would've been tastier if it came out hot. Lastly, I got my surprise dessert where I don't know if I should describe or not to "keep the surprise" for people. I mean... shouldn't they change the dessert every once in a while? Or the menu for that matter. My friend went to Onoir last year and the menu hadn't changed since then. Maybe that's something the restaurant should change? Anyways the dessert was alright. My friend had the chocolate cake and ice cream which I liked better (somehow we managed to share a little with each other).
Overall, an ok experience. I think it's overpriced but people say it's for the experience. I guess at least I can say I've tried it.
