I generally count fast food as a pretty modern thing, and would associate it with some of the more modern societies in league lore, like Piltover. Recently learned I'm wrong about that, it's historically present in some form and even ancient Rome had fast food ( https://www.smithsonianmag.com/smart-news/romans-loved-fast-food-much-we-do-180971845/ for the interested). This got me wondering about fast food in Runeterra. Could Galio really be serving fried chicken in Demacia? Is Shurima into pizza enough to warrent Sivir's violent delivery methods? Do noxian happy meals have spikes on their boxes, and do those have a mortality rate if so? (weeding out the weak)
(generically qualifying fast food as drive-thru/quick takeout style food, although open to discussion about the bounds of that definition)
What kinds of fast food do you think are popular in the different areas of Runeterra?
