Thanks Dalpuri. I just went along with what the restaurant wife suggested to me ie to try mackrel as it was nice with mackrel. Maybe she whould have said that "I think it would be nice with mackrel but I haven't a clue". I'm sure she said that she had tried it in their curry. But the chef then came back and said it hadn't really worked but would be better in a kind of fish chutney. I do sometimes get quite frustrated by being told one thing by one of them and another by somebody else there. I read somewhere that in some countries in Asia, people will give an answer even if they don't know to try and save face or something similar. Maybe there's something like that at play here? And then there's also the added communication problem with their lack of vocabulary and basic sentences when speaking English. But it's an interesting experience on the whole.
