Food has got to be one of the most variable things around.
Fish and chips – I’ve never seen these in a cafeteria. Cafeteries are usually kind of gross, and I’m not sure I’d want to trust something as sensitive as fish to one. The fish, of course, is batter dipped and deep fried white ocean fish, such as cod. Cafeteries have some type of uniform emulsified fish paste with some type of breading material, you know, “fish sticks” and their ilk. Fish and chips stands are/were Great Britain’s most popular fast food – anyone know if they’ve been supplanted by McDonald’s yet? Here in the 'States, they’re a common item in bars-grill types of place, but you’ll never find 'em in a real seafood restaurant. If you want an authentic experience, skip the catsup on the chips and the honey-mustard on the fish, and just go for vinegar and salt. If you’re lucky enough to live near the Canadian border, you’ll even get that wonderful malted vinegar instead (I think that’s what the dark (non-cider) vinegar is, right?
Crisps – really, Hostess makes/sells potato chips in Britain? Always just a bakery company in my mind. Hell, the notion of Wonder Break actually would disuade me from trying Hostess brand chips/crisps/pommes (hmm… pommes is French for apple but German for French Fries while kartofeln are potatoes).
Fries – is there really a standard in the US? Yeah, we all know they’re french fries, but also just fries, home fries, buffalo chips/wedges, freedom fries, country fries, French-fried potatoes, shoe string potatoes, and the whole set of variations again with the word “taters.”
Soda – I’m from Michigan and grew up on “pop” but prefer “soda” – “pop” sounds way too hick for my tastes.
Chocalate sodas are both of those mentioned above, but with the demise of dime/drug store soda fountains Dairy Queen seems to be the place, so ice-cream is by far the general meaning.
Boston coolers are a SE Michigan thing as far as I know, being that you can only make them with Vernor’s. So… Boston? Oh, yeah, what it is: milk is to milkshake as Vernor’s is to bostoncooler.
Malts – malted milk can be tried in Whopper brand malted milk balls.
