We've eaten at just about every Vietnamese restaurant in the greater Cleveland area, and Tay Do in Parma might be our favorite. It's everything a hole-in-the-wall Vietnamese place should be, a true mom-and-pop (she works the front, he the back) establishment. The bun thit nuong, my standard order, is fantastic, as are the banh xeo, spring rolls, vietnamese chicken salad, and spicy beef with tomatoes. It won't win any awards for decor or location (in a truly hideous strip mall) but for anyone in the area looking to experience some real Vietnamese cuisine, this is well worth the trip.
