One word, Hofbräuhaus!!! Fill your gullet full of Bavarian food and "Refreshments"

I've lived for short periods on and off near Munich in the past few years.. in 2004-2005 I was near Stuttgart for all of 11th grade as a Rotary International Youth Ambassador/ Exchange Student. Just last year, March to August I spent a semester on a German University as an Exchange Student. Also, since I was 12, I've been spending most of the summer's with my relatives who live near Frankfurt. Theres tons of great stuff to do. I also recommend that you go to Legoland Günzberg, which is near Munich to the west (if there are kids in tow). Also, if you can, go to Rothenburg ob der Tauber. It's a city that is completely encompassed by a wall. It's an amazing city. I've been there many times. It has a great torture museum amongst many other interesting things, as well as many nice cafes.. Its a short train ride out of Munich.
