I only visited the McD in the city center when I actually arrived in Le Mans in time for scrutineering in 2014. Marginally entertained the thought of buying dinner on Friday from there before heading back to the campsite, because I was not doing the drivers' parade this year, but I ended up buying a can of tuna salad from the Super U in Republique.
...and I still completed it with a crappy beef sandwich from the track.
