Came here for breakfast with my family, we didn't make a reservation but they didn't seem to mind it.
They had a continental buffet going and told us it was the last day, but I opted for the eggs benedict instead (as did my husband). My mother-in-law got the bagel and lox and I got the fruit parfait for my daughter to enjoy.
The meal was good and it felt fancy in there, which was nice. It's conveniently located on the 3rd floor of the Mandarin Oriental so we can go in there at anytime. There's a pastry/coffee shop right next door for you to get pastries, baked goods, coffee and tea to go.
The thing that upset me was that they didn't tell us that the tip was included and we ended up tipping an additional 18%, bringing our bill to $120 for breakfast! Eeek.
