Takoyaki-house Biya is a takoyaki shop in the Sennichimae shopping street in Namba, Osaka, where each order is grilled to order. The takoyaki comes with green onion and is served hot without sauce or other toppings. An elderly couple runs the shop, and each order takes a few minutes because they grill the takoyaki one by one. Skipping the green onion leaves the takoyaki lacking, so adding it is better.
