Has anyone mentioned the David Stone DVD's yet??? WTF - guys, what is wrong with you all? Adding nothing new...just adding to the thread by agreeing with the guy above you. Brilliant! This should be considered thread bumping.
Here is the thing Chrystal, there are many sources that would be good for restaurant stuff...but aren't necessarily focused on restaurant material.
I have found things in Paul Harris' books, Gary Kurtz, Darwin Ortiz...etc....
However, if you are looking for something specific:
Michael Close books or videos called "The Worker's Series" has some great stuff and advice
Paul Wilson's video - "The Restaurant Act", talks about routining, and will help expand what you offer.
Jogn Guastaferro has his Brainstorm videos - cool stuff on them, very commercial
Michael Ammar - Easy to Master Card Miracles...there is a reason these things are popular, GREAT magic - and if you read the credits and listen to Ammar between tricks...you will actually learn something you don't get on most videos...THEORY!
Mark Leveridge has a DVD called "The Art of Table Hopping", he discusses everything from pocket space...to the tricks he does - some cool stuff!
OH - I ALSO HEAR THAT DAVID STONE HAS A DVD FOR RESTAURANT WORKERS! Seriously...WTF
