I'll go to Culver's like once or twice a week. Culver's isn't particularly cheap, and it's not a huge burger, but it also doesn't taste that cheap either. A Culver's Deluxe Single meal is like, I dunno, $10.50 after tax? It tastes good and is made to a fairly consistent standard. I don't get the double stack version (in general, fast food burger patties anywhere aren't usually worth doubling up on; I'd rather get bacon added if I wanted more meat, although my favorite McDonalds burger when I used to go was the McDouble surprisingly).

McDonald's became too expensive for what you get, although the flavor is consistent.
I used to go to Wendy's (who were never as consistent, but generally tasted better than McD's), but by the time I stopped, the only thing I got was the $5 Biggie Bag (which used to be the 4-for-$4), and I remember them doing some shrinkflation bullshit with that eventually, I'd get a tiny-ass soda some days or a tiny patty in my burger, or way less veggies and way more mayo inside.
