On Hamburg’s most historic street, the Deichstrasße, Kartoffelkeller is a cosy, unfussy place which makes a great choice for a simple, warming winter lunch. As the name suggests, it embraces all possible ways of cooking potato: soup, dumplings, pan-fried rösti or baked in foil with a choice of toppings, from mushroom sauce to smoked salmon with a honey, dill and mushroom dressing. There are also seasonal specials, including kale dishes in winter and tender white asparagus (Spargel) in spring. End things on a sweet note with the Rote Grütze for dessert.
Time Out tip: Do take a wander down the Deichstraße and admire some of the oldest surviving buildings in Hamburg.
