Guinness is among my favorites; so to are a variety of English ales -- Newcastle, Bass, Tetley, Boddington's, any number of "India Pale Ales," and so on. I've spent a fair amount of time in pubs in London, and I've concluded that kids (drinking age is 18 there) are the same the world over. The younger customers were drinking cans of Bud and Miller Lite at prices considerably higher than the wonderful English ales. What is difficult (or expensive) to obtain becomes more attractive. When I was in college, people were paying outrageous prices for Coors, because it wasn't available in the East at the time. Now that it's commonly available, of course, we realize it's very ordinary (to give a generous assessment).
