Authentic Chinese and local Chinese

Wakako (Takeda Rina) is inspired to cook after eating Mii-san's (Yamada Kinuo) homemade dish, pork trotters, for lunch, and heads to a Chinese food store in Ikebukuro. There she discovers an authentic Chinese food court next door, and decides to go in. ▼She is unsure what to do as there are a variety of Chinese restaurants lined up, including those from Shanghai, Sichuan, and Taiwan, but she starts by ordering some cold Sichuan skewers and a Chinese beer, and continues to enjoy new flavors. ▼On another day, she visits a local Chinese restaurant and enjoys a delicious dish along with a bottle of Japanese beer - what is this sure-fire dish?!
