Caribou is a chain out of Minneapolis / St Paul (the "Twin Cities"), if I recall correctly. I'm not saying they were particularly good. What I meant was, Peet's was somewhat better, bought out their local locations, and announced that Peet's shops were coming. Instead, in Dad's location, they got another Dunkin Donuts. Overall, I've not heard of Peet's actually opening stores in any of the locations they purchased.
I don't know what's behind all that. But the end result has not been an improvement in product/choice, in our area.
Anyway... I wouldn't have mentioned it, except there was the OP about the Keurig deal. My personal perspective is that if and as Peet's was once a well-regarded set of shops in the Bay area, it's quite another thing, now. As such, Keurig deals and the like not only don't excite me, they engender an actively negative reaction.
Perhaps that says something about putting growth before quality.
If you want good espresso, make it at home. The equipment pays for itself after a few years of not driving out to get espresso on a regular basis.
