Restaurant diners have the opportunity to win big in this new hidden-camera game show. One guest is given instructions via microphone from the maitre d' and must complete five challenges without tipping off the other guests. The stakes and prize money increase with every challenge, but all will be lost if two tests are not completed or the other guests become suspicious and leave the table. From eating off other diners' plates to harassing the wait staff, the codes of conduct for dining in public are being pushed to their limits on "What's on the Menu."
