Wedding 9999,
I belive odie had explained to you, Fullerton is different from other hotels, they provide VIP service. Your food will be serve at one side, then the waiter will divide out individual portions for each guest. Like prawn dish, they only prepare 10 prawns, if you've got 11 guest, 1 guest will go without food, thus need pay extra.
Rokko,
If I remember correctly, my coordinator did inform us we are not allowed to bring outside food into Fullerton for banquet. Whatever things we intend to get, must go through them but of course paying the price much higher to them instead of we getting directly outside. I read the T and C its also stated there. U may wish to check with your coordinator again.
