I have a 5-6 hour layover in Frankfurt, and I would like to get out for a nice morning outing.
I am thinking of an out of this world cup of cappuccino, a nice walk along the water and on cobblestone streets, local markets, warm and friendly people, something vegetarian (vegan + milk products, no eggs) to eat, nothing hectic.
From a bit of googling, Wacker's Kaffee is supposed to have great coffee. Römerberg and Sachsenhausen look very charming. "What the Food!" is supposed to have some vegetarian friendly options.
I would love recommendations!
