For generations, Three Sons served as the defining taste of Italian cuisine in north Denver -- but a few years ago, the place was almost moribund. Then came changes in ownership, in kitchen staff, in menu, even in style, and Three Sons has gone from bad to very, very good. It still looks like a cast-off movie set from some un-produced Godfather sequel, it still smells like garlic all the way out into the parking lot on a good night. But with its new focus on classical Italian cooking and quality ingredients, Three Sons could be a worthy restaurant for generations to come.
