We ate at Zairo our first night in Padova, and it was very good. We were standing outside the restaurant contemplating the menu when a local stopped (she was riding her bike) and urged us to go in. "Is good. Go." We did, and it was. We splurged a bit, but enjoyed our meal very much. DH had vitello tonnato, which is way better than it sounds. I had tagliatelli con fiori de zucchini e capesante - noodles with zucchini flowers and scallops. We split an order of prosciutto with melon, had the house red, and a bottle of frizzante mineral water. I don't eat sweets, and if DH had dessert I didn't note it. Probably not. It was €41 for the two of us. The service was great.
The next night we ate at Antica Trattoria dei Paccagnella, just up the street from the basilica. DH's fried calamari and scampi was excellent. My chicken pasta dish was disappointing; both would have been better with a different wine. (For some reason, we didn't follow the host's wine suggestion.)
We also had pizza at the Ristorante al Santo, which was the hotel we were staying at pre-tour. Good pizza and wine.
