Exactly what you need in a restaurant. The only person you see in the ninja restaurant is the a friendly waiter at the door, ready to seat you, then everything after that is a blur.

You're given a menu with tick boxes, which you tick, you place it on the table, maybe a sound distracts you and you look left, BAM. The menu has vanished into thin air. You wonder about it for a second, maybe a blur to your right causes you to glanc-- *BAM* your table is stacked with food, all piping hot, all expertly arranged, sliced and cooked.

Just finished your drink and placing it down on the table? You maybe feel a slight rustle in the air, look down, your glass has been replenished.

And I’m pretty sure, in the rare case that the steak is overcooked, the chef will come out and perform seppuku.

And if you can't pay the check, no washing dishes, it's mortal combat for you buddy.
