If I had to guess I'd say Cupcakeria Deluxe

Out of this list, the most likely is Cupcakeria Deluxe, Cluckeria and Paleteria are too recent for Remakes. And Fish? Why Fish?

Papa’s Fisheria is one of my fan-made Gamerias that I’m currently working on the ingredients for.

I would guess Burgeria Deluxe if anything; plus, I feel like Sushiria would have too similar ingredients to a potential Fisheria

Kind of, but mine would have ingredients similar to the Cluckeria instead since the fish would be fried in my game.

Burgeria deluxe since it is the only game w/o holidays in any iteration
