Ate here for breakfast twice while staying at the Mandarin Oriental. Both mornings I had the eggs benedict with crab cakes and they were really good. $21 was well worth the price. I also had a $9 cup of coffee each morning which was pretty steep for not being any better than a regular cup of joe.
What did turn me off to this place a little bit was the bland decor. Too much pale wood. The service was good but for some reason the first day we went we weren't offered a side to go with our meal which I didn't think odd at the time. However, the next day we were asked for a side "that comes with the breakfast." How that got screwed up I'll never know.
We were given an amuse bouche the second day as well and not the first. Not sure why either.
Overall food was good but pricey as we expected. $9 coffee, $18 bloody Mary. Two $80 breakfasts. But hey, when in Vegas...at the Mandarin Oriental no less.
