I have a Bianchi Valle, which has flat bars. But, I don't like riding it very far -- I always reach for the fenderless, rackless road bike instead.

However, I've noticed that the Valle has the exact same geometry as the Volpe (probably even the same frame, just different decals), plus it already has fenders and a dynohub -- so I'm planning to get some 9-speed shifters and use some extra drop bars I've got sitting around. I think it'll even be cheaper than if I started with a Volpe and added a dynohub (especially at US prices for dynohubs & lights).
