About us

Bangkok New Siam Food Limited Partnership was established on July 30th, 1990. Located on 171 Soi Ngern U-Dom 1, Bang-Cheuck-Nung , Talingchan, Bangkok.

It was started as a family business by Mr. Udon Yongsiriwan. Mr. Udon used his experiences to improve oyster sauce from family recipe and oyster sauces which were already players in the market to create his very own oyster sauce recipe. His recipe is savory and has unique golden brown color which later became brand signature. The golden brown oyster sauce that provide savory taste, enhance food smell, doesn’t make the food look darker than it should, and can last a year in room temperature before opening.
