Giada is more of a luxury dining experience than it is a good place to eat. A+ on atmosphere and service, C for the food.
You'll never forget where you are because Giada puts her name on EVERYTHING. The tasting menu even comes with a full page photo of the famous chef. The photo booth in the waiting area was fun, and is free to use. I don't see anyone stopping you from using it even if you aren't eating at the restaurant.
The best thing I had were the bacon wrapped dates and the tricolore salad. For all the hype, everything else wasn't really any good. We tried the Chicken for 2 since it was featured in a food magazine, but it was super dry and really nothing special at all. I know Giada doesn't eat a lot of what she cooks, but she probably wouldn't even look at this chicken.
I would also skip the pea pesto crostini and the octopus. You can get much better food at a much cheaper restaurant.
With all the negatives about the food, you can't deny the perfect location on the strip - right on the corner of the Cromwell, and the great service by the professional waiters. It's super fancy.
