I feel stupid when I go here.
I'm a lifelong coffee addict, so I appreciate good coffee, which they definitely have. And although I do appreciate that the staff is knowledgeable, they do come off as pretentious.
I definitely felt pressured to get a plain espresso (which I didn't want to drink, really) for fear of being judged for being uncultured. Then I had to sit in the corner and look like an asshole just drinking an espresso in the middle of the day like it was no big deal. I mean, this is America people!
It was worse for the woman in line in front of me though, who ordered a coffee and asked if they have flavored syrup and the baristas looked at her like she just ordered a side of dead baby.
Basically: coffee is good, but make sure you know what the hell you're doing when you go here!
