thanks for the info, Sher!
the last time i was in touch with the sales manager, he was unfortunately unprofessional and not helpful at all. I asked about outside caterer and he said "no outside caterer allowed" (and he only sent me the buffet menu of 1 caterer), and then when I went for site visit, I realised other functions had other caterers. Only when I asked again then he said they allowed 2 other caterers.
But the menu options were really basic food and I thought quite off for weddings, although I quite like the place.
