I picked up some ice cream there once, probably the best ice cream I've ever eaten. It was completely unflavoured ice cream -- not vanilla -- and really amazing and subtle. Since then I've searched for other "just milk" ice creams, like Fior di Latte and so on, but they usually end up overpoweringly sweet and none have come close to that amazingly simple one in Japan from a small town Lawson's.

Unfortunately it was probably a limited run regional item and I don't expect I'd be able to find it again, even if I went back to the very same Lawson's.
