• Places for cicchetti: Cantinone Gia Schiavi by the Ponte de San Trovaso, not far from Accademia. Try the tapas of pesto with cheese and anchovy with onion (1.15€). They also make bologna sausage and jam paninis for 3.5€. Another nice place is the Osteria - Enoteca Ai Artisti (in the Fondamenta Della Toletta), where you can eat ciccheti seated in their pleasant tables next to the canal. 
• Places for lunch or dinner: Ristorante Agli Alboretti (the speciality is risotto, 30€ per person, near the Accademia), Restaurante Do Farai (specialising in fish, 25€ per person, behind the Palazzo Foscari and Ca Rezzonico, close to the Campo Cappello).
