Let's be honest, we're just setting ourselves up for disappointment making up dozens of awesome Nintendo-themed rides that will never exist. There will be a couple of rides based on Mario and Pokemon and that's it. The food and shops are where the true potential lies here, and I'm a hungry man so let's come up with some sweet ideas for concession stands, restaurants, stores, vending machines, whatever you want as long as it's edible!
I'll kick things off with something small: a Kirby-themed sweet shop (like Honeydukes in the Harry Potter park). Call it Kirby's Gourmet Race or something. It would sell packaged foods, mostly snacks like Doc Louis's Remedy Chocolate Bar (apparently this was already a real thing) and Mario Galaxy Star Bits (they could literally just be konpeito, try to get some honey flavor in there I guess, but it would be a nifty way to introduce this Japanese snack to the West).
Next up, a Pikmin-themed fruit stand. Get a freshly-squeezed fruit juice or smoothie, maybe some Pikpik carrots for good measure, complete with silly fruit names like 'Citrus Lump' and 'Disguised Delicacy.'
Er, then again, "Insect Condo" might not exactly whet patrons' appetites...
Last but not least, the Milk Bar.
Have a glass of Lon Lon Milk or whatever. They serve alcohol too cause y'know milk gets people drunk in Zelda for some reason. Let's get some live entertainment throughout the day from the Indigo-Gos, these guys --
-- and I dunno man how about if KK Slider drops by every once in a while? I'm beat, it's your turn to make shit up now. Have at it.
On a kinda morbid note, I think Splatoon-themed seafood and any kind of Pokemon-themed food at all are probably a bad idea. Might want to steer clear of those.
