Isn't The Henry just their coffee shop/24hr restaurant?
Of those three I'd pick Scarpetta.
We ate at a few cosmo restaurants this past weekend although none of your picks.
Lunch at Comme Ca was good. I can see myself going back. I really enjoyed my pork belly BLT.
Blue Ribbon Sushi was odd. I think the Eating Las Vegas guy said to avoid the fish there and I'd agree. The little we had wasn't bad but was way overpriced even by strip standards and the sushi rice itself was terrible. On the other hand, the fried chicken was pretty good and the oxtail fried rice topped with a bone marrow omelet was very good. My wife is kind of skeeved out eating very much bone marrow, so hey, more for me. The house salad tasted like the salad that comes with every combo meal at every moderate priced Japanese restaurant I've ever been to only with the addition of some watercress and avocado.
Also ate at e' inside Jaleo which was quite an experience. I wouldn't mind trying Jaleo sometime in the future.
