When working resturants you must also consider the following when deciding what effcts to use: size, portability, reset time, overall appeal and suitability for the audience.
Here are some of the effects that I have used with good success... Crazy Man's Handcuffs, Sponge Balls, Chop Cup, Card on the Ceiling, Mike Skinner's Three Card MOnte (Penguin Monte is the same I am told),Coin Matrix,Scotch and Soda,Coins Through thre Hand, Saltshaker Through the Table. Thumbtip tricks.
There are many more I could list, but I think you get the idea... G rated, easy or no set up, variety, surprising climaxes. All of the listed trick can be presented in an entertaining and non-confrontational way. I found that at each table I would perform 3 or 4 effects and move on to the next table. So I had 12 effects as my main working platform and would very the effects from table to table. I worked out of my pockets and out of an apron. I carried the entire 12 tricks with me and had them well organized and at my fingertips. Nothing is worse than a fumbling magician.
