Going to be in Varenna this September for our first visit to that area. Arriving on Friday 9/7 and departing on Tuesday 9/11. I have a friend that said reservations for dinner are essential on the weekends. He was there this same timeframe a couple years ago. Is that typical? We prefer to play everything by ear and usually eat dinner around 9pm or later. I hadn’t even thought of where we want to eat yet. Do I need reservations that time of year?
