A melon bar is a form of employee celebration given at Lumon Industries.

Melon bars are not as coveted as Egg Bars nor are they as rare as Waffle Parties.

They can be small and simple, such as the melon bar brought by Mr. Milchick to welcome Helly to MDR, or they can be large and extravagant like the party thrown to celebrate Burt's retirement from Optics and Design.
