One of the trends I've seen is food bars in grocery stores. They can get fairly sophisticated in wealthy areas. I was house sitting in Oakland county Michigan(auto wealth) some years ago and one could get a pre-cooked filet mignon meal at half the cost of a restaurant meal at one of the high end grocery stores. None of the stores in my metro area serve filet mignon, but you can get a decent meal for $10 or so.
Funny, I’m in Oakland Co. MI :)
Do you recall the store?
