I love the Bun (8.50 and up) at Thuan Loi on 1300 Main St. / Rt 28 in S. Yarmouth. This hole in the wall has authentic Vietnamese cuisine prepared by the owner's sons. The Pho (9.50 and up)is very good too. It's a welcome change to have Thuan Loi on Cape Cod. Closed on Mondays the phone is 508 398 5592. It's close to Doyle's and Riverway Lobster House. I wish they had desserts..
