Near the Ginza (銀座) station of metro, I tried a restaurant whose specialty is xiaolongbao, steamed bun of Chinese cuisine run by Singaporean company. The restaurant is "PARADISE DYNASTY (パラダイスダイナシティ)." Most customers were women at lunch!
Xiaolongbao (steamed bun)
Hot and sour noodle
Jelly and tea
The choice of menu is limited (that's why the price might be reasonable), and lunch is available from JPY900. Xialongbao is of course good, but more than it, I liked hot and sour noodle. The soup was very rich, and combination with chopped coriander was very addictive. My rating is 3.5 out of 5. Gochiso-samadeshita!
