Award-winning actress Julianna Margulies visits Ina Garten at home in the Hamptons. Ina mixes up Real Margaritas to welcome her guest, and they pick herbs in the garden before Julianna has a pinch-me moment -- cooking her signature Halibut with Herb Butter for Ina, who adds a magic ingredient to take it to the next level. To wrap up their special day, Julianna takes the wheel of Ina's convertible and they head to the beach.
