It was during last year on the GDC on some weird place near the convention center. Didn't visit any normal starbucks during the trip. Just enjoyed the $14 or so alcoholic drinks.
I’m skeptical. I live and work in SF and frequent fancy coffee shops. I have never seen $10 plus prices for basic espresso-based drinks, although $4-6 isn’t uncommon. A $10 coffee must of had some other markup applied or been a specialty drink.
I’m not saying SF isn’t expensive. It’s not difficult to find cocktails in the $15-25 range, for instance.
