Apropos of nothing: I moved to the UK eight years ago, and damn, I still miss Trader Joe's. For the most part, I find mid-scale urban British grocery/retail to be much better than its American counterpart (where the industry is too focused on big-box suburban shopping, and to figure out how to do mid-scale/urban right) -- but damn, Trader Joe's is really is the best.
I emailed them a few years ago asking them to expand to the UK. No reply. Alas!
