You won't find much around the station but going towards the city centre you'll come to a large open area and on the other side of that the shops etc start.
This area is on the 'wrong' side of the river but still pleasant enough. Didn't eat that side.
Cross the river into the Via Notari in the main part of town and there is a large restaurant about 100 yards up that wasn't too bad.
The best one we found was to the right of that street in Borgo Stretto. It was called the Nuovo Lo Sfizio (I've just looked for it in her scrapbook so it does come in useful).
Small and cosy with the finest Pannacotta I've ever tasted. Can't remember what else we had but the wife's a veggie and I know she enjoyed hers - and that's a rarity.
There are plenty of other places but not so many around the tower.
