WHAT could more typical of an Italian holiday than sitting in a sun-soaked piazza or the on steps of a grand cathedral, and tucking into a gelato, panino or pizza?

The Renaissance city is cracking down on visitors who eat on footpaths, doorsteps or driveways at lunch and dinner times, threatening them with fines of up to $800 if they do so.
