It might be easy to miss. Just along the initial drag of N Prince St, right across from the Clipper Stadium—there it is on your left: Phở Thanh Thúy, Downtown Lancaster’s one and only Vietnamese restaurant. On the outside, there are few visual hints—no cultural images of rice paddies or sprawling rivers or water buffalo. There is simply a plain white sign reading: “PHO THANH THUY / VIETNAMESE NOODLE HOUSE.”
