i wouldnt do out of this world mostly because while people are eating they dont want to deal cards down and stop eating. also they need space to deal down the cards so they might have to move everything around. lastly, i have found that lots of people know out of this world because when i am doing harry loraynes out of this universe people say "i know that trick!" in the middle of the routine, but after i finish the trick they say oh never mind... i know out of this world... that was a different trick
The big problem with what you've written here is "while people are eating." Generally speaking, in restaurant work, you should not be performing at all for people while they are eating. Your prime performance time is between the seating of the patrons and arrival of the food. Once the food hits the table, you hit the road.
