I live in the neighborhood and Doyle's is my go-to restaurant. I have celiac and have eaten here dozens of times and have never gotten a smidge of gluten. My two daughters are celiac - one is also dairy-free. Same experience for them. Everything on the menu is delicious and I go when I want french fries or fried chicken because the fryer is truly gluten free.
I can't say enough about the kitchen under Nick Bell's watchful eye or the waitstaff as managed by Bridie. Go, you'll be in good gluten-free hands!
