Food & Wine around Penticton, B.C.?

Heading to Penticton where the spouse will compete in Ironman Canada. We’ll be there for 4 solid days total so she can relax, acclimate, get gear in order, etc.

I know nothing about wine in B.C. Any wineries we should check out in the area? Restaurant suggestions? We’ve already got some dinner reservations but could use some lunch recommendations.
