There seems to be quite a resurgence in the humble hot dog down here in London town. Big Apple led the way in making them popular, and they've even begun to creep onto restaurant menus (Delaunay, Hawksmoor, Mishkins and MEATmarket to name just a few I have seen recently). Give it a few months, and you will even get a restaurant dedicated to to dogs when Bubbledogs opens some time later in the year. Slightly less heralded is Herman ze German, not strictly a hot dog retailer, but serving German sausages in rolls is close enough for comparison.
