Flour + Water Pizzeria

Co-chef Ryan Pollnow's mother and sister have coeliac disease, making this an insider-led kitchen. The pizzeria uses a dedicated gluten-free-only oven, separate prep area, and staff change gloves after every build. Multiple coeliac diners (FindMeGlutenFree, Atly, Eater) report no reactions, but two independent sources raise concerns: one symptomatic coeliac reported getting glutened, and another was told by staff they did not recommend eating there for coeliac. No formal accreditation found. Menu marks GF items.

Insider-led, Owner, chef, staff, or a close friend or family member needs to avoid this allergen themselves; kitchen practice reflects that.

Honest caveat: One celiac diner reported a reaction; in another visit staff advised against dining for coeliac.
