My friend and I visited Oma's a few years ago when we were driving from Ontario to Alberta (to get her Ontario car to where they were living then).
A wonderful shop, with a really great owner- she was packing up things to take to a merchant mall, but was so friendly, helpful, and welcoming it was worth the gravel road part of the trip. She also recommended a place to have lunch (when we asked) and it was great too.
I'd go back if I'm in that area again.
