I like most seafood esp Lobster Fugu John Dory aka St Pierre are worth the high prices for me. Crab abd prawns too if by the sea and green mussels.
On the everyday I like Plaice Hake Haddock Cod Barramundi Snapper Bream
Of cured fish Arbroath Smokies ,Smoked, Mackrel, Salmon and of course trout and if at Morrisons Withywood daily fresh Kippers!!
Get in early they are often sold out by 10 esp if I'm in town.
All it needs is a willing smile to the fishmonger's lass my friend, maybe she wll help you fillet, no bones about it.
If You Gurn Hard you may pull a mussel!!
