Tian Yuan Shu Shi Zi Zhu Can is a vegetarian buffet restaurant near Exit 1 of Songjiang Nanjing Station in Taipei. Diners fill a plate with side dishes, pay by weight, and help themselves to white rice, mixed-grain rice, and soup. Food comes out in batches after opening, with the most options at 11 a.m. and long lines at noon. Mold has been found in the food and on the basement seating, so checking hygiene is necessary.
