Steinernes Haus
At this friendly spot, diners share long wooden tables beneath traditional clothing mounted on the walls. The house specialty is a raw steak brought to the table with a heated rock tablet (Stein is the German word for stone) where you do your own cooking. The house beef broth is the perfect antidote to cold weather. By the way, if you order a beer, specify a Kleines, or small glass; if not, you'll automatically get a liter.
