Question 1

Is Oh Nana! safe for people with celiac disease?

Accepted Answer

Yes. Oh Nana! runs a 100% dedicated gluten-free kitchen, the safest setup there is for celiac diners: no gluten in the building, so there are no shared fryers or prep surfaces to worry about. Sansglu scores it 95/100 for celiac safety based on its menus, sourcing, and stated allergen policy. Details on this page were last refreshed May 2026.

Question 2

Does Oh Nana! have gluten-free options?

Accepted Answer

Everything on the menu. Oh Nana! is entirely gluten-free rather than a regular kitchen with a gluten-free section, and Sansglu lists 8 items, including Fried chicken, Tempura, Tofu. For celiac diners that distinction does the heavy lifting, because a fully gluten-free kitchen removes the shared-fryer and shared-prep risk that comes with mixed kitchens.

Question 3

Where is Oh Nana! located?

Accepted Answer

Oh Nana! is located in 千代田区, JP. Pull it up on the Sansglu map to see which other celiac-safe spots are nearby, which helps when you're putting together a full day of safe eating in the area.

Question 4

How does Sansglu verify Oh Nana! is celiac-safe?

Accepted Answer

Sansglu checks Oh Nana!'s own menus, sourcing, and stated allergen policy against how the kitchen actually runs: dedicated facility or mixed, separate prep, fryer policy, staff training. That evidence becomes the 95/100 celiac safety score on this page. Scores of 80 and above are the top tier, reserved for spots where the evidence is most complete. The score is built from verifiable signals rather than user votes; the full methodology is at sansglu.com/about/data. Details on this page were last refreshed May 2026.
