It's Singapore Main Post Office and HQ for Singpost. Including a cinema, shopping mall, many restaurants and cafes. A nice place to go to enjoy the food, watch a movie, but don't go on a Sunday evening. One star less due to the certain service, I myself hate. Take note if you go Singpost, do expect long waiting time (minimum 45-90mins) due to many people. They have many types of services, that why the long waiting time. Beware Do not press the wrong button for the Wrong Q number!!! For overseas shipping service. If you need to sent any package oversea. Must be able to fit their box size requirements and updated international shipping requirements. If not your item package failed the required requirements. You just have to go home and repackaging it and come back again. For any people going there to send items overseas. Please help yourself by checking out online information about how to send items. Don't waste your time and others people time who would be waiting behind you. It would annoyed many people behind you when the calm Singpost counter staffs need to explaining to you, like a child how to post things to overseas. Take note: The shipping cost is costly By air and do bring credit cards along. Do bring a pen, penknife, scissor and packing tape if you going to ship item overseas. Reason is So you can buy their carton boxes, fill in the required documents, pack the carton box, seal it and sent it out. It save you hours needed to travel to post office again.
