VIE has some above-averagely interesting food (soups etc) and lots of Sekt (local sparkling wine), although the lounge itself is rather soulless.
In distance, MUC may be some way out, but by S-bahn it takes about the same time as from VIE to the (real) centre (say Marienplatz in Munich and Stephansplatz in Vienna); the trains are more frequent in Munich, and you don't have to change like you do in Vienna.
