put me in with the 'hate marmite' category.
my hubby sometimes has beans on toast for dinner, if he wants something light. suits me, as long i don't ahve to eat it. i have my spam musubi instead (hey, i'm from hawaii!)
yes, twiglets are evil. however, i have discovered the 'tangy' flavored ones, which is coated with worcester sauce, not marmite, and i can eat a whole bag of them while watching a movie (not recommended, tummyache after).
i'm not keen on shandy. our 'local' serves white wine so i have that or a diet coke (w/ice and lemon, of course!)
i think you'll get used to the food if you're adventurous enough. but then again, there are lots of places around to get stuff that you like. the only thing i miss that i can't get some sort od substitute for is poi.
try gong down to the local butcher's or sasages. our one has lots of different varieties...i tried a pork, onion and sun-dried tomato one...not bad.
