Not why I'm so fixated on this right now, but I remember seeing an episode of an anime or anime inspired show where the the main characters are in some kind of mall and people are super fixated on these plastic wrapped burgers that have a small chance of being golden. Literally all I remember is that it had some kind of monster of the week element in the middle (it had some kind of rolling attack?), and when the main character gets a golden burger at the end, it tastes like crap.

Google has failed me yet again today.

Edit: now that I'm thinking of it more, I think the "monster" might have been some wildman that stole the food.
