It's a beisl, a restaurant, a bar and a beergarden all rolled into one. It's pretty studenty and very old-school, it's been around forever - and it's not very bobo, which is a nice for a change in this area. Very down to earth and also charming; perhaps "rustic" is the word for it.
The menu is greasy and meaty, sweet and veggie; it is VAST, they have everything on there, from Fridattensuppe to Steak, from Schwarzbrot to Palatschinken. They also brew their own beer.
In the warm months of the year you can sit outside on Heurigen-benches. Go there if you want to go out with work-mates or for a quiet chat with a good friend. It's that kind of place :)
