Very nice bar. Music is not too loude there. There are many students even this local isn't in the students district. There you get also many different beers, like the typical styrian Puntigamer beer - my favourite one *g*!
Dress Code: no dress code!
the best spot is the 'Bermuda Triangle' located a little northeast of the Herrengasse and the Hauptplatz. this area got it's name because the people tend to disappear for several hours ,if they enter this dangerous grounds at night. Great collection of pub, cafe's and nightclubs.
One expensive, but very cool places is the M1, located in the top floors of a rather tall building on the Faerberplatz. The view of the terace is outstanding. Can be pretty crowded sometimes....
The interesting thing there is that the people, the cafe's etc. match no certain category. You can find all kinds of people, students, employees worker, and many more. the same goes for the pubs. from cheap and loud, to expensive and romantic, what ever you need you'll find it.
Dress Code: Denpsnds on your choice of pub, no real recommendation.
Flann O'Brien's is a great Irish pub with excellent beer and good food. It's a very friendly place with a lively atmosphere and good music (also live sometimes).
Dress Code: Casual
The local radio station, Antenne Steiermark hold free open air concerts near the university in June, sponsored by local breweries - Puntigamer or Goesser. It is _so_ much fun!
The 'Bermuda Dreieck' i the middle of Graz! In summer you can enjoy the evenings under the moon with a glas of wine or beer. In winter there are a lot of very nice bars.
