Ruoliu Yijin is a noodle shop in Taichung that serves beef noodles and udon in a white bone broth. Its beef noodles come in a mild white broth with tender beef and chewy noodles, while the udon noodles contain several vegetables. The noodles are made in-house, the broth can be refilled, and takeout is available. Weekday lunchtimes and Friday at 5 p.m. draw many customers, so arriving early is necessary.
