Dim Sum factory was founded in 2014 by Janet Lau, a well known entrepreneur and restaurant owner in the Bellevue area of Washington State. Her success in the restaurant business started in 1990, and she has since opened two other restaurants in different parts of Washington. Dim Sum factory is unique in its offerings, which includes Dim Sum, Congee, Noodles, and various types of Asian Tea Drinks.
The history of Dim Sum is usually linked with the older tradition from yum cha (tea tasting), which has its roots in travelers on the ancient Silk Road needing a place to rest. Thus teahouses were established along the roadside. Rural farmers, exhausted after working hard in the fields, would go to teahouses for a relaxing afternoon of tea. At first, it was considered inappropriate to combine tea with food, because people believed it would lead to excessive weight gain. People later discovered that tea can aid in digestion, so teahouse owners began adding various snacks.
The unique culinary art of dim sum originated with the Cantonese in southern China, who over the centuries transformed yum cha from a relaxing respite to a loud and happy dining experience. In Hong Kong, and in most cities and towns in Guangdong province, many restaurants start serving dim sum as early as five in the morning. It is a tradition for the elderly to gather to eat dim sum after morning exercises. For many in southern China, yum cha is treated as a weekend family day. More traditional dim sum restaurants typically serve dim sum until mid-afternoon. However, in modern society it has become common place for restaurants to serve dim sum at dinner time, various dim sum items are even sold as take-out for students and office workers on the go.
While dim sum (literally meaning: touch the heart) was originally not a main meal, only a snack, and therefore only meant to touch the heart, it is now a staple of Cantonese dining culture, especially in Hong Kong.
