I just took 7 to Five Guys yesterday (tweens/teens/young adults - no kids meals here, either)...
6 Cheeseburgers, 1 Hamburger, 3 Large Fries (shared), ZERO drinks - $103.
My kids know this place is their special treat. They had cleaned and sealed my fence, so I was willing to pay them for the work they did...but Five Guys has priced itself into our "special occasion" place, now.
PS - And to be fair to Five Guys, this is b/c they are quality for fast food. But inflation is making them the price of what used to be sit downs...
