The chat show host and her wife Portia de Rossi have joined The Pretenders singer Chrissie Hynde and film producer Steve Bing in investing in the eatery.
The menu will be created by celebrity chef Tal Ronnen - who prepared Ellen and Portia`s wedding menu - and the restaurant`s interior design will be designed by Waldo Fernandez, who has decorated homes for stars including Brad Pitt and Angelina Jolie and Tobey Maguire. The name of the restaurant has yet to be revealed.
Earlier this year Ellen also launched a diet advice webpage, `Going Vegan with Ellen`, with recipes and resources to help users adopt an animal free diet.
Ellen is also juggling her new restaurant plans with the latest series of her self-titled TV show, which she says she continues to work on in the hope of making people "feel good" about themselves and others.
She told Parade magazine: "I think we`ll get a new audience that maybe didn`t watch me because they only watched `Oprah`, and they have a void now. But it`s the same goal whether we have 10 people or 10 million people watching. If we adjust in any way, it`s so we can top ourselves."
On the message she hopes to promote with her show she added: "The world is filled with negativity. I want people to watch me and think, `I feel good, and I`m going to make somebody else feel good today.`
