Greeting from a former Victorian, current Winnipeger. We get out to your town three or four times a year - folks still live in Fairfield, around Beacon Hill Park. It ain't Playa, but it's not a bad place to be about half past February.
The restaurant you're looking for would be Magdalena's, which was run by a mother/daughter duo from Red Deer, Alberta. Regrettably, it's been out of business for some time. It was one of our favourite dining spots. It became Beef E G's, which we never particularly enjoyed, though many others spoke highly of. I believe it's out of business now as well.
