There is a coffee shop in downtown Frankfurt that I always see with a line out the door whenever I go by. BUT, lines mean waiting and I hate waiting. Plus it's just coffee, right? I could not be more wrong.
I went in a few weeks ago and realized that this store deals in the legal version of crack.
I have never enjoyed a cup of coffee so much, nor been so wired from it. If anyone is looking for some really fantastic coffee (or cocoa) in Frankfurt, it's worth the wait.
