For lunch I see people walking around eating baguettes and drinking coffee  The keyword here is WALKING. Also, when Europeans drink coffee, it is real coffee and not some Starbucks shit.  There's a Starbucks in the pedestrian zone by my place, but I honestly can't remember seeing anyone carrying a cup from there... I just looked it up on Google and there's only 2 locations in my entire city. The other one is in the train station. So yeah; it's pretty much there to serve the tourists.
