Cafe Paris is located close to Hamburg's city hall, and walking distance from Central Station, and Hotel Reichshof (http://www.afar.com/places/reichshof-hamburg-curio-collection-by-hilton-hamburg), where I recently stayed.
Built originally as a slaughterhouse in 1882, the building was later converted into a grand turn-of the century French café. It's a prefect place for great french food, in glamorous surroundings. I had an amazing breakfast therre, but they're also known for their delicious seafood platters.
Make sure you also take a good look at the architectural details, outside and inside. The tiled walls and ceilings depict Hamburg's various industries.
Opening Times: Monday - Friday 9am to 11.30pm Saturday, Sunday, holidays 9.30am to 11.30pm
