Lan Ssalguksu is a Vietnamese restaurant next to Samnyonggyo in Guseong-dong, Cheonan. It serves beef pho and a large banh xeo, with bean sprouts and cilantro brought out separately first. The shop is small, with six tables, and on weekend lunchtimes you may wait about 20 minutes before being seated. There is no dedicated parking lot, so cars must be parked on the nearby street.
