Situated in the very touristy Grinzing but a little way off the main attractions, this place offers excellent traditional food and sports a motivated team of extremely friendly waiters. A bit pricey, if I recall correctly, but worth it.
Be prepared to dine with a fair amount of tourists.

Somewhere along the way they must have lost their cook, because nowadays the pizza is average (I don't know about the pasta). I still use it occasionally to take a pizza home, but the glory days of this establishment are gone. Or maybe my taste was less refined when I was a student.

If it the place was less dirty and less populated with weird people I would probably go there more often.
But their gulasch really is legendary. They should start a delivery service :D

k.a. my friends and me) it went by the name "Hexus". This is a long time ago but I assume the basic business of the place is intact, which is catering to young people who like to listen to music of varying quality and sit in a dark place only illuminated by candle light, whilst consuming moderate to large amounts of beer. They made some good food, too.

I also saw a man accidentally set his hair on fire at this place. He was ok though.

The place is in the very middle of Grinzing, at peak times totally filled up with tourists and rich residents, but outside of those times oddly relaxing and soothing, with its traditional interior and relaxed waiters. Very pricey though.
The "non-Martini-Gansl" food is OK, though I have had better.

Food is traditional austrian, good enough, not mind blowing. They have a lovely garden with a huge tree. Their service is a bit slow at times.
