Traveling with husband, two adult kids in their 20s, looking for restaurants in Venice that have a few vegetariand and non-seafood items. Have reservations in San Polo one night (Birraria La Corte) and in Castello for Lunch (Le Tole Spaghetteria). Have also been recommended La Bitta in Dorsoduro -- no online reservations but will try to call.
Would love a few other recommendations!
