Many years I go I went to Dromoland Castle I think in Limerick - we were given battered scampi and I never ever tasted anything like them in my life.
They must have been hand-reared etc as one of the waiters dropped one on the floor and went back into kitchen and carried that "one" on a plate to my friend.
Can you get any nice battered scampi anywhere - I love them.
Trying to compare a corner shop chippy to Dromoland Castle, is just plain daft. They are two very different offerings and it is highly unlikely you will get a similar meal, in taste, atmosphere or presentation. To try and recapture what you had on that day is just going to feed your disappointment.
