Most Frankfurters will tell you this is a restaurant you must visit, and so we did. Always packed with locals and tourists alike, Wagner's is a truly German experience. Start off by ordering a bembel (pitcher) of applewine -those with weak stomachs should however partake in moderation. Then choose from traditional fare like wurst and schnitzel. You may have to stand on your head to get the waiter's attention, but you'll enjoy the festive atmosphere.
