It's my first time going to Mandarin Oriental and having the lunch buffet there, the place is not as spacious as I thought but the variety of food is great. There are lots of sushi, sashimi, king crabs, fresh oysters, salad, and other hot dishes. The best part is the dessert, esp. the dark chocolate truffles squares!
Another thing that surprised me is the price, which is relatively fair, esp. in Central (it’s about 298+10% service charge per person).
