I’m from Yorkshire, 99% of people in Yorkshire wouldn’t have a clue what Talapia is, as it’s rarely available in the U.K. The real deal is always cod or haddock. In fact haddock is the preferred choice in Yorkshire. So if it’s Tilapia at Yorkshire County Fish and Chips, it’s far from authentic.
If you Americans are ever around our parts, for example visiting the medieval City of York or wonderful City of Leeds, have a trip over to Whitby- where Bram Stoker wrote and set Dracula, medieval gothic abbey on a cliff, Captain Cook set sail to discover the New World, and most importantly, the best fish and chips in the world. You have to come north to Yorkshire to get the best fish and chips in the U.K., like the best served beer, although there are good ones dotted around all over the UK. I assume Disney knew this, which is why they called it Yorkshire County fish shop, but if they are using tilapia (which I like) they are besmirching our name.
