Thank you both! I looked at the online catalog for Selfridges and didn't see amedei, but I'm desperate enough to hope that they'll have it if I drop by. I'll definitely check out whole foods also.
I'm looking for a good shop in London that sells chocolate (bars especially) from the best chocolate makers. Specifically, a place that sells Amedei, Domori, etc. is what I'm looking for. I've found plenty of information on chocolatiers in London, but none on stores that sell a selection of high quality chocolate from different makers.
The store wouldn't have to be dedicated solely to chocolate-I'm fine with a larger store (for food or even more) that happens to sell products from Amedei and the like. I'd also like to avoid getting completely ripped off.
