Our favorite thing we did in Salzburg was visit the Augusteiner Beer Hall and Garden. We went both nights we were there. This place is giant and reminded us of a sports arena except the sport is... beer! They have a self service beer counter which is fun if you can figure out the steps. This doesn't seem that difficult, but when you are mixed in with the locals who have been doing this since they were 14 things get tricky.
1. Pay for beers at counter and receive ticket
2. Grab a stein (.5 liter or 1 liter)
3. Rinse stein in the fountain
4. Give steins and ticket to beer man
5. Receive large beer and have a drink! Prost!
Our favorite little snack here was the shaved black radish with course salt! For 1€ this giant plate of spicy/salty radish is the perfect snack to go with a beer.
