Chinese/East Asian groceries in Edinburgh?

Okay, this question isn't really about eating *out* per se, but is there a place in Edinburgh where Chinese groceries and imported Asian (= Chinese, Japanese, Korean) foodstuffs are sold? Maybe a Chinese supermarket or something like that?

I'm going there for a few months on an exchange programme next year! (But I don't fancy haggis or sandwiches or fish and chips or any of that Scottish and English grub. Curry is fine but I'll go on fire if I eat it every day!)
