Two of us are off to Rome for a long weekend this month and the one gap in our itinerary is a restaurant for a nice leisurely lunch on the Sunday. Our taste tends towards modern creative cooking rather than the strictly traditional. For example the highlight of our last Rome trip was a meal at Agata & Romeo. Glass sounds like our "cup of tea" so to speak, and we're hoping for dinner there, but several places that appeal are ruled out because they don't open for Sunday lunch.
Any suggestions much appreciated.
