Had a lovely family meal at Ristorante Pizzeria Al Gobbo di Rialto, just a short walk from Rialto.
We tried a mix of penne, spaghetti, seafood ravioli, pizza, bruschettas, plus a bottle of wine and a cocktail. The service was attentive and the server was very professional yet friendly . The food took a little long (e.g Ravioli was 30 minutes and one had to order at least 2) but was fresh, well-cooked but slightly bland.
We sat outside and the overall atmosphere was relaxed. It was liked by our kids too, which made the whole experience easy and enjoyable.
Overall, a great all-round spot near Rialto not too far from flea market and if you want decent Italian food, good service, and a family-friendly vibe.
