Might try the cod - that's what I get from chippie. My lovely chippie has gone down in its standards so now I am on the lookout for a chippie that doesn't serve fish as large as Loch Nessie's foot. omg
I like hake and monkfish....cod and grouper (groper) you can keep - however, a lovely lemon sole you can't beat (as long as it isn't overcooked) and Conne, frying may have done that to your 'ake.
Have tuna awaiting cooking for tonight. Can't recall having hake. Milder than cod ? I though the taste of cod was hardly detectable. It's why it's shoved in batter of breadcrumbs. Wow.
Haddock is one of my favourites, although Turbot comes a close second. Nothing beats a really nice Sewin though, line caught and consumed in a Welsh country Pub in the Autumn.
