The free event honors Buck's birthday. His star on the St. Louis Walk of Fame sits right in front of Three Kings.
"We did this last year," said Andrew Wool of Three Kings. "The goal was to have fun. We had trivia, we used the red velvet ropes from the Tivoli Theatre to rope off the star and we played old recordings of famous Jack Buck radio calls."
Last year's event was during a Sunday afternoon St. Louis Cardinals baseball game. Tonight's event will be held while the Cardinals host the Houston Astros at Busch Stadium.
Wool said winners can walk away with Cardinals tickets and gift certificates to Three Kings.
"This coincided with the opening of the restaurant last year," Wool said. "It was off the cuff and we had a good response, so we thought we'd try it again."
There will also be birthday cake and the traditional singing of " Happy Birthday" to the star.
