Not much I could eat as a dinner, BUT the shop selling bubble waffles had a gluten-free option! The service was great, and they offered to make a new dough (since they did not have more of the gl.free one). They made me aware of the fact that they used the same iron as the gluten-containing, but that they would clean it as best as they could. Since I really wanted a bubble waffle, I accepted this and did not get any symptoms afterwards:)
