Some seafood places have jumped on the wagon and used that, but to catch your own seafood.
I'm pretty sure entertainment value for the customers will be at a high, and it certainly beats any risk of the chef cheating you since you get to choose which lobster you want to eat.
Who knows, maybe next time, there'll be a scoop instead of a claw, and you catch your own prawns instead? Or reel in your own fish?
What say you?
