Heart Breakfast with JK and Kelly Brook 6:30am - 10am
He's already got a restaurant in Portsmouth, and today - Monday 28th May - Jamie Oliver opens his second one in Hampshire.
The celebrity chef's been telling Heart that Union Jacks in Winchester is all about using British food and drink, even though it specialises in pizzas.
Jamie says he and his business partner will be using local beers, meats and even flour milled nearby.
The chef's also taken on 35 new staff from the local area.
