I have a friend coming for a visit. A Chowhound, in fact. (Hey dude, if you're reading this.) My friend is a vegan. Mrs. Not-a-Plonk-Drinker and I are quite carnivorous in our tastes. Can anyone recommend some restaurants in or around Venice that might satisfy all concerned? My wife is still reeling from a heart-stoppingly dreadful meal at Real Food Daily a few weeks ago.
