I called in advance to speak to the manager, who seemed knowledgeable. He recommended salads or pasta from their gluten-free menu as least risky, since they can be made separately. Their pizza is baked in the same oven as the other pizzas (not on a separate tray), so there is a risk of gluten-containing flour settling on your pizza. I had the impression that the waiting staff didn't take my requests and questions very seriously when I arrived, but didn't have any issues after the meal there. Note that the vegetarian selection on the gluten-free menu is limited (at least without the pizzas).
