Crate & Barrel definitely does use Helvetica, but their logo has one of the more... idiosyncratic alternates in the history of its use. That geometrically circular 'C' has always irked me, but it wouldn't be Crate & Barrel without it.
The actual company logo [1] uses Helvetica (apart from that bizarre 'C'), however the font printed on the back of the plate seen in the article [2] is definitely Arial. Note all the angled terminations.
