CateringDiary.com, catering in Singapore for halal, chinese, indian, outdoor, delivery, western, wedding, corporate, international, creative, florists, event, birthday, tentage, door gifts.
hope this helps! i know it can be madness trying to get ready for CNY. things to buy, dinners & gatherings to arrange etc.
