This restaurant makes it clear that it is not a gf kitchen and that there exists the possibility of cross- contamination.
There is a current GF menu available on their website. I have been to this location of Outback Steakhouse many times without any problems. I typcially have enjoyed one of their signature steaks with sweet potato and a side salad made without croutons with one of their gluten-free dressings. The waitstaff and bartenders have always been very knowledgeable and helpful. I can't speak to other locations, but this one has been tried and true for me.
