30+ years ago, I was working offshore in the North Sea and spent a lot of time in London...where the first Hard Rock Cafe had just opened. I thought I had died and gone to heaven. There was some of the rock and roll memorabilia shtick, but mostly it was about American diner/hamburger joint food, and it was quite good. There were already McDonald's most everywhere, and only the diehard English hadn't chosen it over the dreaded Wimpy (any of those left? I hope not). These days, I would only go to a Hard Rock under force majeure, but back in the day, when we were all younger, it was a welcome reminder of home.
Around that time, I blundered into a Greek restaurant in London that listed pina coladas on their drink list. Foolishly, I ordered one, which was undrinkable-- they substituted gin for the rum.
The other reminder of home was when I persuaded Fortnum & Mason, the very high-toned purveyor of foodstuffs to the toffs, to carry Wolf Brand Chili for me and the other American pipeliners. Cost us about $4 a can in 1974, and worth every penny.
Then when I lived in England again in the mid-90s, this time in Lancashire, I had utterly maxed out on mushy peas, soggy Yorkshire pudding, and fatty/gristly roast beef, when one day, driving on a motorway on the outskirts of Manchester, I saw a beacon of hope-- TGI Friday's. They'd just opened, and I believe it was the first one in the UK and they didn't really have the concept down yet (or at least the waitrons didn't-- but God love 'em, they tried to be chatty and have flair), but they had the margarita mix from the States in stock and the bartender could read directions, and their quesadilla was a dead ringer for its US counterpart. And they didn't charge for refills on coke.
But I also found that both Safeway and Tesco carried a lot of American-type foods-- weiners and hot dog buns, chocolate chip cookies (sometimes the American brands, even...although I always passed them up for my ultimate weakness, Fox Ginger Crunch Cremes), even canned black eyed peas. And around that time, American beer had just started to "invade" England...which was nothing thrilling for me, vastly preferring Heineken or Harp lager, until one day a mate in a pub insisted on buying me a Coors...which was surprisingly good, and surprisingly like Heineken. No surprise, really, since Heineken was brewing it under license in Holland.
