Along the River, Salzburg
Salzburg, Austria. The strip of bars leaves nothing to be desired. The drinks were fairly priced, the company was great, and everyone I met really seemed to like to chat about america and what you've done on your trip.
Dress Code: Dress Tip: Europeans don't wear tennis shoes unless playing a sport, so find yourself a good pair of leathers to wear (That's what I have found at least)
Most of the Salzburg nightlife occurs along the river on the Altstadt side. There's the odd nightclub, a few Irish clubs, etc. It's probably better to start off in a beer garden before hitting the bars/ clubs. The beer gardens are more for the casual drinker and conversationalists (...and beer tasting!).
Dress Code: Relaxed
Head towards the banks of the river in the old town area and you will find there are loads of bars cram packed full with people and with a lively atmosphere. There are 2 Irish pubs and an Australian bar as well as other clubby Austrian places. On the otherside of town in a street off Linzergasse (first street left, where the sausage takeout place is) is a great cocktail bar - Havanna. Go to New Born in Wolf-Dietrich Gasse for live music (often Latin American) with a small cover charge.
Salburg's nightlife is all concentrated along the river Salzach, where you will find many bars and pubs, some of whish are really not bad. There are a couple of Irish pubs, an Australian bar and even a metal bar. Being a small town Salzburg won't offer so much night entertainment for those who are going to spend a long time in town... I spent 4 months there and most weekends I preferred to stay at home with soem friends instead of visiting the same old places...
Dress Code: Casual will be just fine, tehre are a couple of more stylish clubs where preppy clothes are requires. Don't wear sneakers if you're going to enter any club, in Europe they often select on that criteria...
