Danke Dinning in Nagoya, Aichi Prefecture, Japan can help you get your wish, and all it takes is you ordering the Dragon Ball hot pot. No locator, world-spanning search mission, or fights with powerful aliens are required.
The Dragon Balls are colagen jelly with carrot stars - and they're careful to give diners one of each (one star through seven star ball). We can't imagine the insurance rates the restaurant has to pay for all those times a dragon gets summoned in the middle of it. Yikes.
Check out Kotaku for more shots of the Dragon Ball Nabe, and the next time you're in Japan, go place an order and make a wish. You never know!
