Only In Japan ...
... the restaurant offered both fans and blankets, in case you were either too hot or too cold. I imagine you might start with the blanket, but then switch to a fan once the eating got hot and heavy. They also had Q-Tips in the bathrooms in case you ate so much beef that rich, delicious beef fat oozes out of your forehead and gets into your ears. Solidified beef fat in your ears is tres gauche in Japan, after all.
