In the bowels of the old city hall, there is the Ratskeller restaurant. Typical German cuisine, but very tasty and very good quality. Service was impeccable and fast, even though we were there on a Satruday night. Prices are very good, 8-10 EUR for a normal meal, 12EUR for pricier fare, 15EUR for a steak. I recomment to everyone but don't forget to book!
