I avoid fast food as much as possible...
In the past year i just had few fast food meals and they were at: In-n-out, 5Guys, Shake Shack (just the burger, no fries, no soft drink), a Currywrust from a shack in Berlin
I can't enter any of the other fast junk places (MCDonalds, Burger King, Wendy's, Taco Bell,...) the smell of the place makes me wanna through up
