My wife and I were riding our bikes and found ourselves in Waban hungry and Thirsty. We noticed that Stone L'Oven had G-free pizza and gave it a whirl. Had a Glutenberg Blond Ale to go along with it. Pizza was great. I will say I don't get sick easily so I can't attest to super sensitive folks but I was fine.
The staff was really knowledgeable and instilled confidence that everything is prepared separately using different gloves. GF crust on its own pan in a separate part of the oven. And the crust was really good!!
