So I don’t remember how it even tasted because I was so creeped out by the staff situation, but I ate at fatburger once. The old asian lady manager was ordering around the probably high school age girls that were running the registers, directing everything very specifically like the tone of their voice for each canned prase, the angles of their joints, etc. It kept getting more and more weird and gross with stuff like wrist slaps when they didn’t get it perfectly. I never ate at any of their locations ever again.

There’s a local burger place where I live that’s basically an In-N-Out without the branding. Excellent cheeseburgers. The owner even uses locally sourced beef so the burgers are pretty fresh.

Shake Shack’s Shroom Burger is by far the best non-meat burger I’ve had. I’m not even a big fan of mushrooms but Shake Shack manages to turn that portobello mushroom into deliciousness.

Max, Swedens best Hamburgers

Wetherspoons ‘Beyond’ veggie burger used to be the absolute shiznit. They stopped being cheap though, so there’s no real reason to go there any more.

Outback Steakhouse has awesome burgers. A close second IMO, is Smokey Bones burgers. They are mostly on East coast US.

I don’t eat fast food.

the problem is there are levels to fast food. I see some suggestions that would be casual dining restaurants and then there are sorta shiek places like 5 guys or buffalo wild wings. What I consider fast food that has burgers around me is wendys, mcdonalds, burger king, arbys, culvers, and a&w. Of those I would consider wendys the clear winner. Culvers is a close second and three decades or more ago burger king would be in the running. I often forget how decent a wendys single is till they have a deal and I get one. One thing though is since the big inflation hit I have only picked up fast food single digit amount of times and usually because I just have to (last time was related to my wife being sent to the er from the doctors office during a procedure.)

Nexx Burger and Burgerlords but I’m vegan so it’s they’re only the best available to me in Los Angeles.

It kinda depends, and my opinion has to be tempered with the knowledge that not all chains are everywhere. That means the only white castle I’ve had was frozen, I’ve never had in n out, etc.

What chains are present within reasonable driving distance, or that I’ve had elsewhere are: sonic, Jack in the box, McDonald’s, burger king, Wendy’s, Hardee’s/Carl Jr’s. You can add steak n shake, cookout, and five guys, if you consider those as fast food (I do, but some don’t). I’ve also had what-a-burger when visiting family, though not often.

There’s more than one kind of burger, which makes it difficult.

As an example, Hardee’s does these burgers that are huge, and supposedly black angus beef. Amazing burgers for a fast food joint. Arguably as good or better than burgers at sit down restaurants, including steak houses (depending on which one). But they’re a specialty burger, and that’s not always comparable to standard burgers.

And there’s a difference between something like a big mac, that’s piled with stuff, and a regular cheeseburger.

So, for my money, my actual favorite fast food burger of any kind is Burger King’s regular cheeseburger. It’s just the small patty, a slice of cheese, a few pickles, nurses mustard and ketchup. Simple, enough so that your really taste the beef, but the toppings serve to enhance that flavor rather than cover it up (which is what happens with whoppers and big macs). Plus, the size is more reasonable. I don’t feel bloated by one, even with a drink.

However, the Frisco burger from hardees is bomb. Sourdough bread rather than a bun. Not the best sourdough tbh, but it’s still a decent enough attempt. The bacon and tomato work well with it. Not a fan of mayo, so I would order it without. Haven’t had one in ages though, because they’re freaking huge. 800+ calories, and it’s like you swallowed a handful of those sponges in gelcaps that kids take into the bathtub with them. It’s too much food.

Those would be my top picks for a fairly standard burger though. One smaller and kinda generic, the other a belly buster that’s sorta specialty, but not a vast departure.

That being said, there’s a style of burger I’ve had when visiting family that’s called “Carolina burger”. It’s the toppings that make it a style, not the burger itself. Chili sauce, onion, slaw, mustard, with pickles optional. The chilli sauce is not standard hamburger/hotdog chili. It’s its own thing, with hundreds of recipes, at least. Every family does their chili sauce different. Definitely the best regional burger I’ve had.

The best Carolina burgers are not fast food available anywhere except at a whataburger, and they don’t call it that. I looked it up, and they call it a hamburger and the bigger version is a what-a-hamburger. Which, it’s important to note that this is not the same chain as is in Texas. This is just a couple of joints in one town in North Carolina. I’ve only ever been to them with my cousin a few times, but holy shit is it good. They also make this strangely good drink concoction called a witch doctor, which is basically every drink they have, plus pickles and pickle juice. But they’re technically a drive-in and sit down joint, not a proper fast food joint, but they are just as fast as any of that big chains. It’s worth the trip just for the burger though.

Not that fast food burgers would be my pick for a burger 90% of the time, though.
