Having McDonald's and a hot dog in Florence

Sometimes guests who are visiting us, have a longing for American fast food. I think it is difficult for people to totally change their diet, even if the new diet is delicious and healthy.  So for those readers out there who are visiting Italy and have a hankering for American fast food, here are some comments from my guests.

The McDonald's in the train station has a regular American menu and the food tastes like it does in the U.S.  The store is clean,  the bathrooms are free and the security guards forcibly run off the gypsies who ply their trade. 

Hot dogs, with mustard, (sorry no relish) can be had at cafes. The cost is about the same as it is in the US.

Any comments from others who have eaten American fast food in Italy?
