Gluten-Free is on the menu, but the same kitchen also prepares what you avoid, so cross-contamination is possible. Tell staff what you react to, and ask how your dish is prepared before you order.
A long-standing Graz Gasthaus with a gluten-free menu of its own, where the kitchen will prepare breaded dishes gluten-free on request. Gluten is cooked here too, say so when you order.
