Up-n-Atom Burger is a fast-food restaurant featured in Grand Theft Auto V. Its tagline is "Once It Pings, Eat Like Kings", and can be seen on the side of a truck driving through Los Santos. One it's main competitors is the Burger Shot.
- Up-n-Atom is likely based on the Western U.S. hamburger chain In-N-Out Burger, with the new name being a pun of the phrase "up and at 'em".
- The atomic structure next to the tagline is in the shape of male genitalia, keeping with the tradition of Rockstar's sexual humor.
- The tagline refers to Burger King, which is already parodied as Burger Shot. The yellow curve up over the Up n Atom name is reminiscent of both the In-N-Out logo and McDonald's "golden arches."
