A typical burger + fries + drink at McDonalds where I am in the US is now about $20. You can get something much better quality (& larger size) at FiveGuys for same price, and even some nice quality restaurants have lunch specials that cost the same.

McD was never good, but when it was $10 it was still an OK occasional convenient lunch option. At $20 there is zero reason to go there.

That’s bonkers. I’m on the east coast (not nyc) and a quarter pounder medium meal is $10.49. Meanwhile Five Guys is $20.29 for a regular meal.
