I've been a pinkberry fan since the 1/2 hour lines in the ONE ORIGNAL LOCATION in West Hollywood. There's a whole story about that which is pretty fascinating:
The Taste that Launched A Thousand Parking Tickets (LA times article)
Now there are a bunch so, less lines. There's one walking distance from my office (in Koreatown, of course!). Yes, it rocks rocks rocks. We get it at least once a week (usually more like twice a week). It's deeeeelicious!
Although there's all this debate about what it really is . I still think they need a commercial with a white background a la the mac ads, having "real" people guess what Pinkberry is, and right in the middle Charleton Heston says "PINKBERRY IS PEOPLE!!!!!!!"

Now that's some frozen bliss right there.
