First off, air Fryers are for sissies and should be smashed with sledge hammers (the sissies too). You want a lotta fat and grease to make a good cheeseburger. Personally I've made some pretty good ones but none reaching the pinnacle of perfection that I've experienced at some eateries.

Now if you're talking low-fat or no-fat or grass-fed beef or veggie-burgers, kindly stop reading right here and go hug a tree or have a freaking harmonic convergence with your fellow Democrats cuz you don't know what a good cheeseburger is anyway. And quite frankly, if you're a Democrat you don't know your ass from a hole in the ground anyway about anything.

Long story short the best burgers I ever had were at a bar in DC that was called either The Capitol Grille or the Capitol Brewery and Grille, I don't remember which one it was but a cab driver took me to the wrong one one time and that's when I realized there were two with similar names. The other one didn't have good burgers though.

Another one that comes close is Brumley's in Greeneville Tn. I try to stop there anytime I'm in the area but you have to have reservations and they don't open 'til 5pm. They're in the General Morgan Inn there.

As far as fast food burgers, there are none better than In 'n Out Burgers in my opinion but they're only available out west. Don't go to feces-covered California though, you can get them in AZ and Vegas and other places out west.
