While Zac Efron got to go to London to promote "High School Musical 2," his onscreen dad got a trip too -- all the way to a Papa John's Pizza in Edgewater, Maryland.

TMZ TV's buddies at "Late Night with Erik Haase" caught Bart Johnson at the grand opening of the prestigious pizza parlor, and boy was it a madhouse!

There are no small roles ... only small pizzas, right?
