Not defending the price of a cup of coffee at all, but as someone who roasts their own coffee (both cause I love the process and am a cheap bastard), its only fair to point out the price of green beans is almost exactly double the price it was 3 years ago.

Again, plenty of ways to slice the astronomic price, but at the end of the day I would only half blame the restaurant here on the mark up
