If you're thinking hotels/resorts, I'd say there's more to be found on the Adriatic coast of Emilia-Romagna but the foodie dimension may be a little more classically aligned with the Parma/Modena/Bologna axis. That said, the seafood on the Adriatic coast can be great and there are some very good restaurants. You might want to try viamichelin.com and do a hotel (and restaurant) search there. I tend to trust their hotel recommendations more as they send professional inspectors.
