I agree. I find Kölsch really boring if I have to drink it all day. But there are alternatives in Cologne. Braustelle do some interesting-sounding beers, only one of which I have tried: Rosemarie, a rosemary-infused amber lager, and very nice it was too. And Freischem’s Brauhaus[/url:3lh8ppab] (no need for the apostrophe in German, my wife says) does a passable stout (the brewer's parents are from Liverpool). That reminds me, I have a voucher for a free beer there!
