Jon Armstrong's L&L DVDs are a very useful set if you are interested in strolling/walk-around/or restaurant work. I really don't remember seeing anything in these DVDs that were too complicated, and most of the tricks take up very little space to perform. But then again, I have friends that work in the restaurant business and that do corporate strolling magic that perform effects like the Chop Cup, and the Malini Egg Bag, and I never thought you could get away with those in walk-around and restaurant but apparently you can with enough practice.
If you would like some insight as to the quality of the magic on Jon Armstrong's L&L DVDs, pick up Reel Magic Magic Issue #11 for 10 dollars, he performs and explains a trick from there called "What If?". That one trick sparked my interest enough to invest in the set and I was not disappointed at all. A wonderful collection of magic, and some concepts introduced on those DVDs I have never heard or read before. It's definitely worth checking out if you have the money to do so.
