First time I ever went to a traditional Japanese cook-house I couldn't believe to variety of food. Moreover, I couldn't believe the variety of food that was still moving...
Yeah I know what you ean! I have been to one before too and it was awesome! 
All of the food tasted so good, but I couldn't get over how recently they killed the courses. Still-moving octopus? No thank you.
haha, yeah I know what you ean, but at least you know it is fresh!
