Had an amazing Chinese restaurant near my old place, really excellent food but always completely deserted. They always seemed so surprised that when we called for takeout and whenever we collected it they'd chat about how busy they'd been, and how bus loads of tourists stop by, it just happens to be empty right now... Uhuh. Surrre. I live in this street, I don't see busses of anyone. But the food was consistently excellent, so they must have actively not advertised because otherwise they'd been super popular.
