Be prepared to share this schnitzel!
Everybody told me to eat German sausage, pretzels and schnitzels on my virgin trip to Germany (Munich), but to me, those were information easily found off the internet. I wanted to try something not-so-well-talked-about, and yet is something the locals would say, "Ja, it's our local food."
Be well-rested for long walks.
If you are easily bored out by repetitive stuff (i.e. Mozart here and Mozart there), or are short of time, spend time on Makartsteg bridge (just off Mirabel Palace) and soak in the beautiful sight of Salzburg along the riverside.
