Had brunch here on our visit to Vegas.
The Good:
1. Nice location inside Paris Hotel. Ask to sit in the outdoor terrace or the glassed in terrace. Beautiful Views.
2. Service was excellent
3. Food choices were plenty.
What we had:
1. Quiche (with squash and spinach) - Just OK. We've had better.
2. Cinnamon "pancake" is actually a crepe - excellent!
3. Chicken, brie, spinach crepe - just OK
4. Breakfast Americain - with scrambled eggs and bacon - just OK
5. Coffee was just OK
Overall, depending on what you get food can be hit or miss.
You are mainly going for the atmosphere and the experience so take it all in.
