Great place for breakfast, my recommendation is the Hallenfrühstück: Ham, poached egg, spinach and to top it off small pancakes with fresh fruit.

Try to go there when the sun is out, breakfast outside is even better.

Update: Here's a new favourite: Mexican Breakfast. Tortilla's with black beans and scrambled eggs, ham, salad, sour cream, guacamole and Pico de Gallo.
