The city of Love - Really

I know Paris is called the "city of Love" but does that include a booth at McDonalds? Having paid for a "closet", I mean hotel room for $125 bucks a night, I now understand why there are so many people out in the open and not in their room. Heck it's almost too expensive to even get a booth at McDonalds. 6 euros for a Big Mac Meal - or about $9 US dollars.
