We went there on a Sunday for the all vegan brunch and the staff happily showed us the available gluten-free options (13€ plate+bowl, 21€ all you can eat). Drinks can be had with soy milk with no extra charge. They also have a variety of excellent homemade gluten-free cakes which are clearly labelled.
