Catching up on some reading while I have time here in Scotland.  This topic intrigued me...let me say a 'proper' fish & chip dinner is nothing like what you are talking about.   So far my experince with fish & chips over here is less than all the hype.  
To make a proper fish & chips... take a nice fillet of something, use a batter that has almost no flavor, and fry...Add the chips which are potatoes cut into 1/2" wide strips under cook them slightly, serve with mushy peas and maybe beans over the fires.  vineager is the condiment of choice usually or maybe brown sauce, which is a thin gravey of sorts with little taste.
:P
I suggest if you travel to Europe bring tabasco sauce, salt, and cyanne with you to improve many of the dishes served.
I have spent about 8 weeks this year in the UK, and will not make a BW trip this year, I love reading about the experiences others are having.
What I would give to have your fish & chips travlinman.
