"Raising money for kids who need it is great, man," Ortiz said. "That's the way we roll with things, and as long as you're helping people, there's nothing better than that. That's the way to go. There's a lot of people out there that need help from people like us, so if I can do it, I just go for it."
The event runs from 11 a.m. to 2 p.m. ET and tickets are $150. Fans interested in attending calling 212-461-4083 or online at www.DavidOrtizChildrensFund.org/eatngreet.
The lunch will feature a photo opportunity with Big Papi, lunch provided by Big Papi's Grille, an auction and a raffle.
"People are going to like the food at my restaurant," Ortiz said. "We're always fixing things up just right there. But just to do this for a good cause and helping people out and things like that, I think it's good."
The latest item from Big Papi's kitchen -- peach mango salsa -- will also be launched at the event.
Fans who can't make it to the event can still contribute to the David Ortiz Children's Fund by purchasing a raffle ticket for their chance to win David Ortiz autographed memorabilia and Big Papi's Kitchen new peach mango salsa. Raffle tickets are $10 and are available online at www.DavidOrtizChildrensFund.org/eatngreet.
The David Ortiz Children's Fund has raised more than $1 million.
