This year's Slider Challenge in Dublin's historic district offers an extended menu.

The fourth annual event, which runs from 1 to 4 p.m. Saturday, July 8, at Bridge and High streets, is sponsored by the Historic Dublin Business Association this year and boasts seven featured restaurants - two more than were on last year's menu.

Tucci's is returning, and newcomer Harvest will be featured for the first time.

Additional participating restaurants include Dublin Village Tavern, J. Liu Restaurant & Bar, La Chatelaine French Bakery and Bistro, Mezzo Restaurant & Bar and Oscar's of Dublin.

A maximum of 250 tickets are available for the event, which typically sells out every year, said Christena Wentz, the business association's coordinator.

"Even if you come once, you won't get the same thing next year," she said.

Prizes for best slider sandwich include Judges' Choice and People's Choice awards, Wentz said.

This year, judges include Dublin City Councilmen Christina Alutto and Tim Lecklider, a representative from Cameron Mitchell Restaurants and a grill master.

Last year's Judges' Choice went to Mezzo, and the People's Choice went to La Chatelaine, Wentz said.

Proceeds of the event go to Welcome Warehouse, a non-profit organization providing support to Dublin and Dublin City School District families who are financially struggling.

Welcome Warehouse Executive Director Jean Griffith said the organization is "thrilled" to be the beneficiary of this year's slider challenge.

"We are grateful to the Historic Dublin Business Association and the Dublin community for their generosity, and for the opportunity to raise funds to support our work helping local families," Griffith said.

Tickets are $15 and can be purchased at Chelsea Borough Home, 54 S. High St., leading up to the event or at the corner of Bridge and High streets the day of the event.
