Fatburger is a globally franchised fast-casual restaurant chain. In 1952, a woman named Lovie Yancey started making burgers in Los Angeles garage and a legend was born. Fatburger is named for its 1/3 pound, juicy burger, but also serves Veggieburgers, Turkeyburgers, and Chicken Sandwiches. Fatburger makes their onion rings fresh everyday and uses real ice-cream in their hand-scooped shakes. Fatburger’s greatest claims to fame are the toppings and add-ons that are available, which far exceed the ordinary burger-joint options. Fatburger patrons can get their burgers with mustard, relish, onions, pickles, tomato, lettuce, mayo as standard fare. But the Fatburger can be supplemented with cheese, bacon, chili, an onion ring, an egg, or extra patties. The ultimate Fatburger order is the Triple Kingburger; which features two additional patties and all the add-ons. Fatburger is renowned in hip-hop circles. It has been mentioned in the songs of Ice Cube, the Beastie Boys, and the late Notorious B.I.G. Today Fatburger has more than 80 franchise locations in places as distant as Hong Kong.
There's nothing quite like a Kingburger when you really need a Fatburger fix.

1. A hamburger consisting of three (or four, sometimes five) beef patties, each topped with a cheese of your choice. The meat is slapped on a huge bun, and can be topped with other things (onions, mustard, ketchup, pickles, etc.) May also be called phatburger in some areas. Not usually found in chain restaurants, but a staple of greasy spoons on the corner. The burger called a fatburger because of its size, and because eating a lot of them will probably make you fat.

2. Depending on where you get it from, it can be the best burger you'll ever have....when it's cooked properly.
