Here's an ad that ran in the Lorain Journal on November 27, 1957, suggesting celebrating Thanksgiving at the Airport Tavern instead of cooking at home. (I don't know if Mutt & Jeff's – current occupant of the Tavern's former digs – offers that same option tomorrow. I'll have to ask our favorite server Brenda.)
I've never really eaten out on Thanksgiving, although the day may come someday. The closest I ever came was one Thanksgiving when I was single. I bought a rotisserie chicken at a Convenient Food Mart (the folks were out of town).
Today, rotisserie chickens (from Apples on Lake Road) are one of the spouse's and my favorite meals when we don't feel like cooking. For a truly Canadian meal (the spouse is a Canuck you know), we mix up some Swiss Chalet sauce to dip the chicken in.
