Actually I had been to Munich before this last weekend. When I was a student in Edinburgh I took a train tour of Germany, I think I went to Munich. I only remember trying to work out how to buy a ticket for the S bahn. I also went looking for a vast beer garden around a lake. I had this fancy of walking around a lake hold a massive Stein of beer. I never found the lake. Now that I think about it, it was probably the English Garden , which is more garden than beer garden.
In my first trip to Munich I did manage to visit a beer hall. I only remember a German guy asleep with his head on a table from too many beers. I don't remember seeing so many American tourists last time.
