In his final few months alive, my Dad was pretty much locked up in the house and wouldn't let anyone in other than me. I'd check in on him a few times per week, and bring him groceries and cigarettes. Sometimes he'd have me stop off at McDonalds to get him something to eat. I remember one time, he wanted a Big Mac and I figured what the hell, I'll get myself one too.
I bit into it and thought man, this is actually GOOD! I think it tasted good though, because it had been freshly made. And, it had been ages since I've had one, so it was a nice change of pace. But, I also remember those suckers were $5-something apiece back then, and thinking McDonald's wasn't exactly cheap anymore.
When it comes to fast food, my preference does tend to run towards Wendy's, above Burger King and McDonald's. Sometimes I like Arby's, too. But, that stuff does get expensive.
When I go to my car shows in Carlisle PA, in the evenings my friends and I will usually hit up a local sit-down diner or restaurant. Usually for around $20, including the tip, I can get a meal that leaves me stuffed. Often I'll just get water instead of a soda, to keep the tab down, but then add that amount, more or less, to the tip. That might not be the best comparison though, because Carlisle is a lower-cost area, so restaurant prices are a bit lower than what I'm used to.
