The morning ceremony at the burger joint, which features the slogan "What You Crave," involved a flower girl who threw salt and pepper packets instead of rice, and employee name tags on the grooms' lapels.
The cake resembled a White Castle tray holding three "slyder" burgers, fries and a drink - all made of cake and frosting.
Cyndie Nunamaker of Plain City, 17 miles northwest of Columbus, said she and new husband Brian Wilson opted for the alternative wedding because they love White Castle.
The nuptials were broadcast live on a local radio station, which paid for the flowers and other arrangements.
