Those numbers look quite wrong, I don't think they're comparing like-for-like.
For consumer goods it seems they're comparing a cheap UK supermarket to Whole Foods in SF, and for rents they must be ignoring square footage and/or using different definitions of city center to get those comparisons. I checked out rental prices in SF on a recent visit and found SF pretty good value compared to London.
