Akaoni (Red Demon) is a popular (with the gaijin crowd) all-you-can-eat yakiniku restaurant located on the 6th floor of the same building that Hamazushi is in.  It's also one of the cheapest yakiniku restaurants we've ever encountered, thus accounting for its popularity I'm sure.  At least, the lunch prices are very cheap, dinner is more of course.

No leftovers allowed!

The setup is that once you pay you take trays and plates and go to these walk up refrigerated shelves that contains various raw meats, vegetables and sundries.  Load up, and go back to grab rice, soup, and water (there's also an all you can drink option that costs more).  At your table you cook your own meat and then rinse/repeat until either your 60 minutes is up or you are stuffed.  60 minutes is less time than you  might think if you are cooking your own food for 3 people.  Nonetheless, we did manage to get quite full.

Pre-cooked food

The ambience of the place leaves much to be desired.  There were tons of people (all gaijin) and it was a big echoey room, and the resultant din was truly deafening.  I had to shout to be heard and had to ask people to repeat themselves constantly.  Also, the decor (or lack thereof) was decidedly uncharming.  It has an institutional feel...like what an old-folks home would look like if it decided to implement yakiniku style meal-times.

Cooking food...

I don't usually care too much about ambience provided the prices are cheap and the food is great.  The food quality, however, is not great.  We tried lots of different meats and ended up preferring the chicken and thicker pork slices.  Everything else was tough or flavorless.  My wife and I both felt rather unpleasant for the rest of the day after eating there (we were *not* sickened though).

And this was in the bathroom...

Our overall impression was quite negative.  I can see why people like it (cheap and convenient), but the negatives overpower the positives in my opinion, and I don't really want to come back if I can avoid it.
