I have to imagine Universal got a look at the insane demand Pokemon Cafe has with there being an Osaka location. Obviously not a 1:1 idea, but it might genuinely be insane to pass up the opportunity for a similar concept that might well sell tickets for the park on its own. That would definitely have to be a table service setup, and with the demand they would still need a high volume QSR/two smaller QSRs (which is the current situation minus insane demand for the TSR).
I also wouldn’t be opposed to Thunder Falls becoming a TSR permanently, though I would like to see the type of foods it typically offered available elsewhere in IOA if it did. That space is beautiful and it would feel natural for it to be a TSR given the “location” it’s set in.
