I'm not a fan of seafood in general, I like fish and chips but anything else like tuna, anchovies, sardines, crab, crayfish and calamari make me want to spew.
That Hawaiian pizza I ordered in a restaurant in Portugal had the tuna hidden under the melted cheese so I didn't know it was there until I took a bite, as soon as I realised it had tuna in it I almost gagged and spat it out.
The Portuguese love their seafood but I don't know what they were playing at putting tuna in a Hawaiian when it's just normally ham, cheese and pineapple.
When I complained to the waiter he pointed out that tuna was listed as part of the ingredients on the menu but the menu was written in bloody Portuguese.
Despite all that Portugal is still the best country I've traveled too, I can't recommend it highly enough, great people, great beaches and great beer.
Just a pity they can't make a decent Hawaiian pizza.
