Am going on a cruise departing Venice in late July with five other couples from college; all in our early 50's. We're not particulary adventurous eaters, but want to go somewhere off the tourist path (authentic/local place) where we can eat for less than an arm and a leg and have a good time (much wine drinking, celebrating, etc.); any ideas/suggestions? Thanks. Trattoria level ok, fancy formal dining not a must but should be above paper place settings. Thanks.
