I ate here a few times. It's not the most charming place - very old school Austrian interior. In summer, you can sit in tbe garden outside which is quite lovet. They have a separate GF menu with plenty of choices of Austrian dishes, incl. Schnitzel and desserts. The food arrives with a cute "glutenfrei" flag, tastes good and I was fine every time so seems to be safe.
