From a world where White Maple Land was real, "Iggies"; the best iguanodon burger in the world.
For the future, "Babyburger"; succulent FauxFlesh human veal, tank cultured for purity, finely ground, seasoned and served in a high fibre bun.
Also known as 'Terran Veal' ("The other white meat").
"Splurge". Another futuristic fast-food joint, this one sells nothing but various flavours/combinations of "splurge", a cake/bar hybrid that's inflated by gas producing an aerated cake with multiple layers.
Try the mustard beef with strawberry jam and cream, it's a classic.
