I honestly didn't know that there was even such a thing as National Tenya Day but boy am I glad that we were able to see the banner informing people about it since Tenya is actually one of the few places that we enjoy our Tempura from.
Sadly, I wasn't able to take a photo of the banner because we were busy trying to make our way inside.
We ordered two of the large classic tendon and one regular classic tendon. The photo below is a regular one. I realized that the difference between the two sizes was just a bit of extra rice.
