If I Opened a Restaurant

With it's 30+ million people, the Keihin area (Tokyo and its neighbors) is booming with businesses that have to somehow distinguish themselves from others. You see this most often when it comes to the food industry. There's no limit to the originality and innovation of the restaurants you'll find in Tokyo. Just take a look at the Themed Restaurant tag on my blog and you'll get a good idea of what I mean. And I haven't yet even scratched the surface of the matter at hand.
 The thing is, what keeps these businesses running is not only the owners striving to differentiate themselves, but also the great number of people aching for something new. And with a metropolitan area with this many people, one needs only to pick people's curiosity to have a steady flow of customers.
 Which gets me thinking that, if I had the capital to start up, I could open something really fucked up that would have curious customers rallying to my shop's door. Here's a few ideas!

1. Merry Go Around
A restaurant where all tables are round. Customers order as usual, and, when the food arrives, their chairs start revolving around the table, moving along a track! What a great way to share food when eating with a group of several people, all the while making sure one asshole doesn't hog all the good stuff.

2. Firing Squad
Customers grab an apron and place their order then line up against the wall with their mouths open. The food is then thrown at their face by something similar to a baseball pitching machine.

3. Hunger Games
Everyone pays the same price to enter the restaurant, and receives chopsticks, a fork or a spoon (chosen at the entrance.) They then stand in a room with a timer above head, and, when the timer hits zero, a door opens and they must all rush into the next room (a 50 meter dash or so) which has a great amount of food at its center. First arrived gets first pick. Everyone has 2 minutes to eat as much as they can before they are urged by the staff to go back into the previous room and wait for the timer again.

4. Gravity
By most means a regular restaurant, except customers are strapped to a chair suspended from the ceiling. Pregnant women aren't allowed entry.

5. Limelight
Ten juries (paying customers, maybe 2000¥ each) are placed at a table with lots of food, but are not allowed to touch it at all (or else they get kicked out and replaced by another paying customer.) Then, a "performer" (another paying customer, 2000¥) must dance or sing to impress the juries (less than 2 minutes per performance please.) Depending on how impressed they were, the juries give you food accordingly. Every 3 performances the juries are swapped out by the next batch of paying customers. Performers get to take their food to the next room.

THESE IDEAS ARE MY INTELLECTUAL PROPERTY NOW. DON'T STEAL MY IDEAS.
