I love this place. I've been here about 4 times and every experience was pretty nice.
I would recommend coming here for brunch and breakfast. It's relatively cheap (about 40 dollars for two people) and the food is good. Recently, I ordered the french toast which was really good (about 12 dollars).
During dinner, for two people the bill was about 200 dollars. However, we ordered quite a lot, including oysters, steak, duck salad, lamb (I think), sparkling water, truffle fries and dessert. The ambiance is dark and romantic, but honestly, I believe there's better value for dinner elsewhere and the food good, just didn't have a wow factor. That being said, I still had a good time and the service was excellent.
One bonus is that at night, after dinner you can take a little stroll through their pool area right outside Buchon. It's quite nice and quiet.
Overall verdict, come here for breakfast and brunch. I don't believe they take reservations for brunch.
