Fullerton hotel, sunday champagne buffet, S$118 with champagne, S$78 without.
very nice (of coz, it's so expensive. but if it's boss paying, a different story right :p). got lots of oyster, lobster, sashimi, duck, cheese, and DESSERT! i think they should offer dessert buffet for women, as it is really good quality and big variety of desserts there. the champagne is also very nice, but dun drink too fast if it's your first time... better drink juices there.
btw, next time will try the chocolate buffet there. heard it's also very nice. 8-11pm daily.
