I've tried Daniel Boulud a couple of times and it wasn't all that I expected. I believe we just ate there each time because the other fine dining restaurants were full and weren't taking anymore reservations.
I've had fish with wine and my date had some kind of poultry with wine as well. We weren't all that impressed. Tell you the truth, the couple of other times I ate there I don't remember what I ordered because nothing was all that fascinating and I wasn't in awe.
The first time we tried it we sat inside which was okay. The second time around we ate outside which was very beautiful with the waterfall and the water show that comes on every 15-30 minutes. After sitting outside the second time, I've always sat outside. From time to time, you'll see celebrities come and dine there. Once, I was dining outside and Dean Cain came and sat right next to our table. I believe that was the only highlight of that day which says a lot.
If you are planning to dine at a fancy French restaurant I would recommend Alex @ The Wynn next to Wing Lei. Although, Alex may be a tad bit more expensive.
