If you want a burger in the DC universe, then there's only one place to go: Big Belly Burger.
That's definitely the case on The CW's Arrowverse, with both Jay Garrick and Harry Wells commenting or asking about the presence of Big Belly Burger on Earth-1.
It also appears to be the food of choice Zoom gives to Caitlin when keeping a prisoner, a callback to Team Flash doing the same for their prisoners, and there's even a poster for it in Harry and Jesse's quarters.
