Up-n-Atom Burger
Up-n-Atom Burger is a fictional fast-food chain in Grand Theft Auto V (2013) and GTA Online. GTA Wiki says it is modelled mainly on In-N-Out Burger, with a tagline echoing Burger King. Its restaurants, trucks and ads dot Los Santos and Blaine County, but players cannot eat there.
What is Up-n-Atom in GTA V?
Up-n-Atom Burger is a retro burger chain with an atomic-age theme, found across Los Santos and Blaine County in GTA V. On the in-game LCN stock exchange its main rival is Burger Shot.
Its mascots are Ray and May, who, according to GTA Wiki, are also the couple who founded it. The tagline "Once It Pings, Eat Like Kings" hints at microwaved food.
What does Up-n-Atom parody?
GTA Wiki names In-N-Out Burger as the main inspiration: the Vinewood Boulevard branch copies the real In-N-Out on Sunset Boulevard in Los Angeles. The "Kings" tagline nods to Burger King, and the yellow arch above the logo recalls McDonald's.
Where are the Up-n-Atom restaurants?
GTA Wiki lists branches on Vinewood Boulevard, Las Lagunas Boulevard and Clinton Avenue in Vinewood, two in Del Perro, and two around Procopio in the north of Blaine County.

Can you eat at Up-n-Atom?
No. The restaurants cannot be entered. The brand lives on as scenery: delivery trucks on the roads, billboards and vehicle liveries in GTA Online. Snacks and drinks from shops and vending machines, where brands such as Sprunk appear, are the everyday food in GTA V.
