Street magic is performed, amazingly, on the street corners. It is done by itinerant people as a means of getting tips. Some call this "begging" because you are doing "tricks" (usually gimmicks that are quick but entertaining) and asking for money. It is not begging but in some jurisdictions you can be arrested under the "panhandling" laws.
Just to stick up for all my street magic friends...
What you said is technically correct, BUT you make it sound like street magicians are fly-by-nighters who divy their time between 30 second D'lite performances, begging for cash, and running from the cops.
That's just not fair.
For many people, street magic is not only an art form but also a way to support themselves. In reality (unlike David Blaine specials) buskers usually do full shows of 20-30 minutes, and are (by necessity) MUCH more skilled than your average hobby magician-- they do not simply rely on "quick but entertaining" gimmicks. When they do collect a hat, it is far from "begging." In fact, there is porbablly more "art" in the process of a busker "passing the hat" than in most restaurant magician's entire repertoire. Though technically you can be arrested in some places, most performers carry liscences to perform and are completely legit.
I apologize if I misunderstood what you were trying to express, but street magic is one of my favorite magical genres.
And to address the original question (as if it hadn't already been)-- street magic and restaurant magic are very different things.
