OKO - Fun Okonomiyaki Bar

All okonomiyaki here are wheat-free, made with okara powder, and cooked on a separate grill with dedicated utensils. The owner Screenshot operates solo and is widely reported to have excellent knowledge of coeliac needs, with signs posted about cross-contamination precautions. However, the kitchen is not 100% dedicated — some items contain wheat (standard okonomiyaki for non-GF diners) — so cross-contact risk, though well-managed, is not zero. One symptomatic coeliac reviewer reported a bad reaction, reinforcing the need for caution. Classed as strongly trusted: dedicated equipment, trained staff, and a clearly marked menu (GF items are flagged), but with a shared kitchen.

Strongly trusted, High-care setup. Either someone close to the kitchen (owner, chef, staff) needs to avoid this allergen themselves, OR the menu marks allergens AND dedicated equipment plus trained staff manage cross-contamination.

All okonomiyaki here are wheat-free, made with okara powder, and cooked on a separate grill with dedicated utensils. The owner Screenshot operates solo and is widely reported to have excellent knowledge of coeliac needs, with signs posted about cross-contamination precautions. However, the kitchen is not 100% dedicated — some items contain wheat (standard okonomiyaki for non-GF diners) — so cross-contact risk, though well-managed, is not zero. One symptomatic coeliac reviewer reported a bad reaction, reinforcing the need for caution. Classed as strongly trusted: dedicated equipment, trained staff, and a clearly marked menu (GF items are flagged), but with a shared kitchen.

Honest caveat: One symptomatic coeliac reviewer reported a bad reaction despite ordering from the GF menu, suggesting occasional cross-contact. This is not a dedicated facility.

Strongly trusted, High-care setup. Either someone close to the kitchen (owner, chef, staff) needs to avoid this allergen themselves, OR the menu marks allergens AND dedicated equipment plus trained staff manage cross-contamination.

The venue is widely described as vegan-friendly, with a separate vegan menu available on request. Vegan okonomiyaki is made with okara powder and uses no animal products. However, the same grill is used for non-vegan items containing meat, seafood, and eggs, so cross-contact is possible. Staff (the owner) is reported to be knowledgeable about vegan needs. Classed as strongly trusted: dedicated menu and aware staff, but shared cooking surfaces.

Strongly trusted, High-care setup. Either someone close to the kitchen (owner, chef, staff) needs to avoid this allergen themselves, OR the menu marks allergens AND dedicated equipment plus trained staff manage cross-contamination.

Vegetarian options are available from a separate menu, and the venue is tagged as a vegetarian-friendly restaurant. The owner accommodates dietary needs. But the shared grill means vegetarian dishes may contact meat/seafood residues. Classed as strongly trusted.
