It sounds like a pretty smart business plan -- customers are always concerned about how fresh their seafood is, so why not just allow them to fish for their own dinner? In Japan, chain restaurant Zauo has its customers fish for their food, then asks them how their catch should be prepared (sashimi, grilled, simmered or fried). Plus, if you successfully catch a fish, you get a discount.
This isn't quite like being out on a lake with a canoe and a fishing rod though.The diners/fishers can see the fish with no problem since the water is clear. And, according to the video below, the fish bite pretty easily.
Customers even sit on boats, rather than dining tables, to eat.
Watch the catch-and-eat process below.
