Sure it's a marketing ploy for fast food, but we're suckers for oversized anything.
A McDonald's in Peru wants you to feel like a kid again, before you had to worry about things like saturated fats and clogged arteries, and when Chicken McNuggets were a birthday feast. So they installed a massive counter to give their customers that child-like feeling of wonder all over again. Just be careful with the hot coffee.
Side question: Gigantic furniture is my jam (I loved the Chicago Field Museum's display of a massive kitchen table and chair, Shaq's massive art exhibit, and others). Are there any other gigantic furniture places you can recommend?
