I found one store which sells delicious chinese dim sum with cheap price! The store is packed with many local chinese people always. And the store always has very fresh and hot pork buns and steamed shrimp dumpling. I bought three steamed shrimp dumpling, three veggies and shrimp dumpling, three pork bums and something that I don't know the name. Can you believe total price was about $5- (about 400 Japanese yen!) Must go when you visit chinatown in San Francisco.
The store is on Stockton street, between Jackson and Washington.
