Actress Sandra Oh is winning her battle to convert her Grey's Anatomy co-stars to veganism, after treating them to a lunch at her favorite animal-friendly restaurant.

Oh took a bunch of cast and crew members to Truly Vegan in Hollywood on August 1st, and wowed them with a menu of meat-free delights, reports Star magazine. And her plan to cut meat out of their diets is working.

A source tells the magazine, "They couldn't believe how amazing the food tasted. Patrick Dempsey enjoyed the chocolate vegan cake and Ellen Pompeo has gone to Truly Vegan half a dozen times since trying the food."
