Sottangja Malatang is a Sichuan restaurant near Songpa Station that serves mainland Chinese-style malatang and guobaorou. Customers choose ingredients such as ham, Vienna sausage, wood ear mushrooms, vegetables, corn noodles, and beef, and select a spice level. On weekday afternoons around 6 p.m., students form a line, and the store is kept clean. The shop is small, so arriving at the wrong time means waiting.
