Worked in Whitby for a while, live in Redcar. I can honestly say that none of the fish and chips shops are any better than at home.
If I was in Whitby, my choices would be- Riverside opposite Parkol, Railway Chippy, on Fishburn Rd, which is up behind the hospital and nick, or Royal Fisheries which the locals call Fruscos on Baxtergate, all of these are places the locals tend to go.
In Redcar, I would go to Seabreeze Oliver’s, or Fishermans Square, the Little Chip wasn’t bad for a while but the portions are ridiculously small. That said, the best ones are gone- West Dyke fish and Chip shop or my favourite of all time was Thames Road in Redcar, the queue outside was as long as the one for the Holgate.
Redcar is better for fish and chips than Whitby.
