OKO - Fun Okonomiyaki Bar
Every okonomiyaki served at this venue is wheat-free, made with okara powder, and cooked on a separate grill using dedicated utensils.
Per-allergen evidence
Every okonomiyaki served at this venue is wheat-free, made with okara powder, and cooked on a separate grill using dedicated utensils. The owner, who operates solo, is widely reported to have excellent knowledge of coeliac needs, and signs about cross-contamination precautions are posted throughout the space. The kitchen is not 100% dedicated, however, because some items, standard okonomiyaki for non-GF diners, contain wheat. Cross-contact risk, though well-managed, is therefore not zero. One symptomatic coeliac reviewer reported a bad reaction, which reinforces the need for caution. The venue is classed as strongly trusted due to dedicated equipment, trained staff, and a clearly marked menu where GF items are flagged, but it operates with a shared kitchen.
