Something about hearing about a British person eating tacos seems very odd and off to me.

When I was in Europe in the early 60's the only Mexican (well, U.S. version of Mexican) food was two restaurants in Madrid, next to each other. Both owned by a retired US Navy Petty Officer. Similarly, there were guys in my Kaserne in Frankfurt, Germany, which would pool their money to take a taxi to Heidelberg for the only A&W Rootbeer Drive In. They all thought we Yanks were as nuts as you think of Brits eating Tacos.

I also remember being in Minneapolis back when the closest you could get to Mexican was canned tortillas at a specialty grocery.
