I have yet to find seafood that I like.
Irony of ironies is that I love fishing. Luckily anything I catch worth keeping my wife is more than happy to eat.
People always tell me that good fish shouldn't taste/smell fishy. I retort that I suppose good beef shouldn't be beefy either.
I'm willing to hear people out, try different fish prepared in different ways, still haven't found one that I liked, at best they're mostly tolerable.
I've figured out that I generally tend to enjoy freshwater fish over saltwater. If I catch a couple nice trout I'll eat that for dinner with my wife instead of having to make a separate dish for myself, I won't hate it, but I won't like it either and I'd probably rather have a hot dog.
And I like raw fish better than cooked.
I might actually kind of like raw oysters, but they are in no way worth the cost.
Lox isn't bad, but I'd prefer just about anything else over it.
There are a couple fish-based products out there that are so far removed from fish that they're hardly worth mentioning for the purposes of this comment that I do enjoy, like Worcestershire sauce and Asian fish sauces, katsuobushi, Caesar dressing, Crab Rangoon (let's be real, you could probably leave the crab or "krab" out of most takeout rangoons and it wouldn't change much) some Japanese fish cakes, etc.
The absolute worst is shrimp though. Nothing about shrimp is appealing to me, the taste, smell and especially the texture are all pretty repulsive.
I'm not otherwise a guy with a lot of food hangups and consider myself a pretty adventurous eater. Weird tastes, textures, bizarre fermented stuff, strange meats, etc. are all generally OK in my book, there's not many other foods out there that I don't enjoy. In my house right now I have some double salt salmiak licorice, a bottle of Malört, a wide selection of hot sauces going up to around 1 million scoville, I'm pretty sure I have both Vegemite and marmite somewhere in my fridge, some very peaty scotches, and plenty of other very divisive foodstuffs that I enjoy.
I have tentative plans to visit Iceland next year, so I'll probably end up torturing myself with some hákarl at some point. And I don't intend to seek it out, but if it happens to be offered to me for free somewhere I may consider trying whale, which I suppose is technically seafood.
