Madhulika Sikka

Underneath railway arches on a nondescript street in North London, you'll find an old warehouse that's the epicenter of the Ottolenghi food empire.

Jerusalem-born food impresario Yotam Ottolenghi and his business partner, Sami Tamimi, started out over a decade ago with one restaurant in London selling fresh, Middle East-inspired food. The business now encompasses several restaurants, an expanding online food business and some cookbooks that have been wildly successful on their home turf and here in the U.S.

Yotam Ottolenghi and Sami Tamimi own four wildly popular London restaurants and have authored runaway best-selling cookbooks for omnivores and vegetarians alike.
