Kim kitchen and Le Xin are my favourite tingkat caterer, especially Le Xin with no MSG, that is perfectly fine for us at age above 30.
I normally order mini buffet from 338 Catering and Shi Fu Ge catering, perfectly suits many of my family members' taste buds.
I order buffet from Yeh Lai Siang Catering, Mei Hao 99 and House Of Catering for special events in my family and office.
