My wife and I are having dinner tomorrow with a colleague and his wife tomorrow night. We're staying in mid-town. He likes traditional Italian food. I like good food, good wine and moderate prices. We're not after a trendy, cutting-edge restaurant (like a Mario Batali place). Anywhere in Manhattan is fine but mid-town to the village is better. Someone suggested Nanni's Restaurant on East 46th but I've never been. Also, we'd prefer casual dress. Thanks in advance.
