I have eaten regular fish n chips and the scallop dinner at Cooke's.
Cooke's is very bland food. If you like bland, fried food, it's the place to be.
(The fried Doh bar was horrible. Sounded so good. But don't waste your time or the calories. Just eat a Snickers candy bar. It's much better.)
Have not tried the fish n chips in UK pavilion.
