Good Burger (restaurant)

The Good Burger restaurant is a fast food restaurant and the main setting of Undertale. Mondo Burger was their competitor before an overdose of Triampathol in the Mondo meat supply made the building collapse.

Details
Although clearly played off as a joke, Good Burger is an insanely unsanitary restaurant, as evident by employee Spatch. As Jesus is an incompetent cashier, and other employees claim that they can't take inside orders because "that's not their job", it's a miracle that something like Ed's Sauce could save the restaurant from Mondo Burger.
