For those who don't know what okonomiyaki is, it's what is often referred to as a "savory pancake", though I've often seen it as more akin to a floury omelette. This is a very poor translation as it tends to be a much messier and complicated mess than a pancake. The idea that a convenience store can craft a version that you can eat with one hand is not so much revolutionary or evolutionary as de-evolutionary. I can't see this as anything but a step backward in food craft, and the description of this specimen only supports my sense of this.
The image above this paragraph is from a box of Osaka okinomiyaki sembei that I reviewed in the past. That is what okonomiyaki usually looks like and you can see that it's a complex affair which in no way resembles the slab of substances above with an egg on top.
The Mini Stop version touts its fluffy texture as well as the fact that there are wieners mixed into the dough. Wieners. I'm no expert in okonomiyaki, and I know that there are tons of regional versions, but I've never heard anyone talk about wieners in their Japanese pancake. They also mention that cabbage, bonito, and sausage (all flavored with soy sauce) are a part of their handheld abmonination.
Honestly, the whole thing as a food item doesn't sound that bad. In fact, it does seem that it has potential to be a unique savory option which would be good for a quick morning meal as long as you didn't care about your cholesterol levels. As handheld okonomiyaki, well, it's kind of like selling pizza rolls as if they were actually pizza.
