Cappuccino with Renzo

This weekend is our first (and in theory only) free long weekend, and most everyone is headed out of town. After much floundering I've settled on Cinque Terre with the last night in Genoa, though we are still trying to make reservations for 3 at short notice. Any suggestions? I'm starting to get really excited about a relaxed "vacation" this weekend just at the edge of tourist season, and a visit to the hometown and workshop of the one and only, Renzo Piano. It's still in the works, but I'm hoping they'd be willing to let us tour around.
