Non-NY fast food places have gotten close to or breached $10 for the burger. I still remember the “six dollar burger” at CJ.
When I was a teenager, I was in a boarding school (1975 or so). When we went on trips, we’d get $2 for lunch. At McDonald’s, I could get 6 cheeseburgers and a Coke for that (I was a teen. I had no problem, eating them all).
