The Gordon Biersch Brewery Restaurant Group is gassing up Octoberfest celebrations by giving patrons a chance to win a Volkswagen Beetle. Through Nov. 2, 25 Gordon Biersch locations around the country will have a Beetle parked in front. Guests can register at the restaurants. Each location selects one finalist. The finalists have to roll six dice marked with the letters B-E-E-T-L-E. If all six dice spell “Beetle,” the winner receives a $20,000 check good only towards the purchase of a Volkswagen. If no one spells “Beetle,” then no dice on the car. Patrick Henry Creative Promotions Inc., Houston, TX, handles
