Dim Sum Service Philosophy (点心茶楼文化)
Guangdong Province — expanded in Hong Kong in the 20th century
The yum cha (饮茶 — drink tea) experience is as much about service philosophy as food. Traditional Hong Kong and Cantonese dim sum teahouses operate a specific sequence: hot tea ordered first; steamed items first; fried items mid-meal; sweet items last. The push-cart service culture is a specific Hong Kong innovation now being replaced by order-form systems.
