Are there any shops in Sheffield that sell the silver can/bottle version that is currently available in Bia Hoi and Dev Cat?

If you cant find anywhere in sheffield euro-beer (www.euro-beer.co.uk) will have it. I think they can get lager/beer from any country in the world.

EDITO :- There an off-licence near the leadmill,cant think of its name,but i know they sell quite a lot of imported lagers so you might want to try there.

Sapporo - toughest can EVAR!!!

The Japanese restaurant on London Rd sells Sapporo in brown bottles. I don't know if they have (or can order for you) the silver can version.
