As you leave the basilica behind, I highly recommend you stop by the restaurant Finisterrae, either for an aperitivo, a drink, or even a cup of coffee (depending on the day!). It will be a perfect end to this day in Florence, observing the piazza and the basilica as you sip on something. Bonus points if you get to see the piazza during golden hour as it becomes even more beautiful in the golden rays of sunshine.
