September is mild shoulder season, good for Rheinauhafen, Ehrenfeld, and day trips to Bonn.
City overview
Cologne sits on both banks of the Rhine, with the Dom, Altstadt, Belgian Quarter, Ehrenfeld, Suedstadt, Deutz, and the rings tying Roman history, medieval churches, breweries, museums, carnival, and river bridges into one compact city. The cathedral dominates the arrival from Hauptbahnhof, but the local identity comes just as much from Koelsch beer halls, neighborhood squares, and Karneval season.
Food & drink
Cologne food centers on Koelsch beer, Himmel un Aad, Halve Hahn rye rolls with Gouda, Reibekuchen, Sauerbraten, blood sausage, and brewery snacks served by fast-moving Koebes waiters. Brauhaus Frueh, Paeffgen, Sion, Malzmuehle, Alter Markt, Zuelpicher Strasse, and Ehrenfeld are the first food-and-beer map.

September is comfortable for the book-fair city, Westend parks, and Sachsenhausen tavern nights.
City overview
Frankfurt is a Main River finance city with a compact rebuilt old town, a serious museum bank, and skyscrapers that make the skyline feel unlike any other German city. The traveler frame is Römerberg and Altstadt for history, Sachsenhausen and Museumsufer for riverfront culture, and Bahnhofsviertel and Westend for the dense urban edge around the Hauptbahnhof.
Food & drink
Frankfurt food is tavern and market-focused: Frankfurter Wuerstchen are slender smoked sausages, gruene Sosse mixes herbs into a cold sauce for eggs and potatoes, Handkaese mit Musik marinates sour-milk cheese with onions, and Apfelwein is poured from blue-grey Bembel jugs. Kleinmarkthalle, Fressgass, Dauth-Schneider, Lorsbacher Thal, and Textorstrasse taverns add schnitzel, Bethmaennchen, and cider-house meals.
