We loved Munich! We took a private walking tour through Tours By Locals from this guy, who is an American expat living in Germany:

We stayed at the Palace Hotel, which we loved. Also there is an amazing high-end grocery store almost across the street, with a wonderful restaurant upstairs:

The English Garden is their version of Central Park and is great for strolling and picnicking. Don't miss the artificial surfing wave!
