This solid bar in the Niederdorf has all the classic cocktails you could want and a respectable choice of spirits like vodka, rum, bourbons and single malts, but you can just as easily sip a beer to get into the mood before an evening out. The outdoor area facing the lively Rosenhof Square is one of the lovelier spots in town and as Regenbogen serves burgers, pasta and sandwiches you don't even have to move elsewhere to eat once you've settled in. DJs and bands occasionally perform to ensure that you don't get too relaxed on a fun night out.
