Friday Spark : Der Licious, the vision of German food in the US?

Der Wienerschnitzel is a Fast Food chain which first opened in 1961, specializing in hot dog (which quite does not reflect in their name, as wienerschnitzel are not at all hot dogs...). Now that hot dog are following the burger trends in Europe, will Wienerschnitzel be an example to follow?
