Chef Extraordinaire
I too got to travel to England for a class when I was 20, many moons ago. The most memorable food I ate was prawns in an avocado with that special pink sauce, I had that whenever I could. Our instructor also took the class to Simpsons on the Strand, where we had roast beast. Most of what we ate was pretty bland.
Marie Rose sauce? Love that stuff. An Irish pub near us used to serve it with fish and chips. Then it closed and reopened with a new chef who serves it with ordinary tartar sauce. We haven't been back. It's no longer special.
