My mother would eat here every sunday from the age of 11, and the halibut and fries from Duckworth's was akin to mothers milk for myself and my 2 sisters. I go here often still, and the place hasn't changed a bit!! Even the lady at the counter has been there as long as I can remember (and still wears her make-up exactly the same LOL)!!
The fish is always crispy on the outside and moist on the inside, though, I wouldn't eat here if you have cholesterol issues. It's artery-clogging goodness!
I'll always come back to Ducky's, as my family calls it, and my children have been raised on their food as well, starting a 4th generation off right :)
Eat in and have the bread and butter. It's always been a favourite with us :)
