I stopped at Cannon Coffee in Hagerstown, MD on my drive from Ohio to Washington, DC on 6/7/22. Everything is gluten-free! They have waffles, some toasts, and bagels (and some bowls, but I didn't focus on those so I can't tell you what they were 😅 - granolas or grains, I think?) And of course, coffee and teas. I opted for a banana, strawberry and chocolate waffle for a sweet afternoon dessert, and it was very good.
— Yes, the establishment is dedicated gluten-free
