I'm on the west coast but the prices aren't much cheaper elsewhere if at all. It's way cheaper in Japan to get ramen, but probably much more expensive to get sushi, which is maybe the last value oriented quality meal I'm usually able to find. Canadian A&W and Popeyes are quite good as well (I found U.S Popeyes lacking flavor and juiciness), but never ever get combos at fast food places, only the burger. McDonald's is tasting more and more like cardboard while their prices rise.
Right around When "smash" patties started becoming the next millenial fad is when I first started seeing absurd prices like that. Sides stopped being included, and I ordered a double patty at a local place, paid $16 for just the damn burger, felt insulated, and then just left. I continue trying to keep an open mind, but I tend to be skeptical that I'll get anything worthwhile for my money. If only I'd had a huge amount invested in stocks when the value of money halved.
