I grew up by the sea, when DS was younger and we were home on holiday, we would go out to a well known fishing village on the north side of Dublin, he used to eat oysters fresh off the boat, he was about twelve and the trawler man I should be charging for these but it is a delight to see a young child so adventurous, he ate about 15, the trawler man was refusing payment, I said Ok thank you very much and nipped into the "If it swims we have it shop" ( for all north siders they used to be in Marino) they were retailing at £1.50 each (albeit in Euro), I insisted he take some payment, the following year he recognised DS, and said he can have them, but they have to be free, my wife killed me for taking money from such an adventurous child. 
Anyway long story short (always the Irish way, the long that is, not the short
, the only thing he has yet to try of any note is lobster.
He has had oysters, crab, periwinkles, cockles the lot, but not lobster..
We are going to Cote on Tuesday where is going to try the lobster and frites and thanks to Rishi there will be a tenner off.
I am fairly sure it will have been previously frozen, but it will give him an idea.
If he doesn't like it, no big loss, we should have been on holiday this month, so even EOTHO we haven't scratched the surface of what a holiday would have cost us, so bring it on.
