One great thing about visiting these major cities at this time of year is that they are not swamped by tourists. You really do have more of the city to explore as you won’t need to line up at museums that would usually have you spending at least 4-5 hours of your time queuing. So you gain all this time to enjoy the city and fit in a couple of extra features that summer visitors normally can’t. There is one place that will usually have a queue no matter what time of year, It’s a tiny little institution for lunch a few steps for the central markets (mercati centrale di San Lorenzo) called Mario. Every Florentine knows about it, and the astute tourist will do their best to find out about it. It’s hit or miss whether you will find any artichokes on the menu but that shouldn’t stop you from having lunch there. They aren’t open at dinner so you need to schedule carefully between museum or church visits.
