Bei Oma Kleinmann is a small Cologne institution with a neighbourhood feel. Their specialty is schnitzel. Big schnitzels. Schnitzels with lemon...or mushroom sauce...or a fried egg. Yep, we're not kidding. Come with an appetite or after a few beers, trust us on this one. Walk in and give your name, grab a cold kölsch and wait patiently until a table frees up. Stick around for another nice cold Kölsch in the traditional ambiance after dinner - it's open until 1am. As a tourist or as a local, Bei Oma Kleinmann is definitely a box you have to tick.
