Castello 4738. Just 8 minutes from Piazza San Marco (200 m NE), this small and atmospheric restaurant/pizzeria will absolutely enchant you. Famous for its traditional style pizza and seafood pasta, you will not only get it all at affordable prices (pizza from €7.50, pasta from €10, wine from €5/half litre), but you're also served by a most friendly and hearty staff. They top it off with a free home made digestivo (mostly vodka and lemon) at the end of your meal, just to make 100% sure you'll be coming back for more.
