Perhaps being steeped in tradition, the folks here quite liberal with the rules so they allow people to smoke.
Not sure if it sounds like a good deal to you but this more than a century old unagi-ya permits indoor smoking. This implies that a meal here might be ruined when a bunch of salarymen popped in and start to smoke before, during and after meal.
Signature Kinshidon (Omelette over eel rice)
Opened since Taisho period, this Unagi-Ya is said to be one of the most famous or perhaps respected shop in Kyoto. Since day 1 of the operation, they have been consistently grilling the eel over long charcoal and this process can still be observed through the kitchen window at level one. But I have reservations whether the unagi the food tasted better with longer history as the homemade tare (sauce) of the unagi here was slightly too diluted and the portions of the eel were meagre. This is relatively compared to Nodaiwa in Tokyo.
