Restaurant Brewer Mühlen Kölsch. Typical food of the region and great beer. Address: Heumarkt 6. I think even Bill Clinton ate there once. The Heumarkt is known by everyone, so easy to find.

Just one warning. This weekend is Carneval Weekend. Cologne is one of he biggest Carneval cities in Germany. All restaurants and pubs will be full with cheerfull and later the evening drunk people.
