The best fish and chips I ever ate were at a little F&C cart in Port Townsend. That was about 25 years ago.
Recently, my best F&C's was at a chip truck located on the main street of Ucluelet. The fish was very fresh, batter excellent and the chips were fresh cut.
I also had excellent F&C's on the ferry dock at Quathiaski Cove on Quadra Island. Really fresh fish and excellent fries.
In Tofino, Big Daddy's Fish Fry is always a must stop.
The worst in recent memory was at the Grizzly Paw in Canmore, Alberta. The Haddock was Tilapia, I'm sure and the fries were frozen. The micro brew beer on the other had was excellent. Lesson learned, eat fish on the coast not in the mountains.
About 30 years ago we ate F&C's on the beach in Stonehaven the night before we started on our cross Scotland hike. We bought our F&C's at the famous chippy that invented the Deep Fried Mars Bar. Take a Mars Bar, dip in the same batter as the fish, drop it in the same oil as the fish. Enjoy if you're Scottish. I'm not. Scotland, great place to eat if you like grease, don't like veggies and plan to die young.
