I was visiting Sankyu's website the other day (http://www.sankyu.ca) and noticed they had a blurb up announcing that their Stony Plain Road location was closing, due to staff shortages. Date of closure is listed as November 21, 2008. I had only recently discovered their downtown location, so might try to squeeze a visit in!
Sankyu 2 Go on Jasper Avenue remains open. Their menu from Stony will not be carried over to Sankyu 2 Go.
