Best Pistachio Cake in OC?

I’m getting a friend’s parents a cake as thanks for inviting me on a trip to Vegas recently and I’ve been told by him that they like Pistachio, Dark Chocolate, and Cheese which made me think of a Pistachio Chocolate Cheesecake or something. Any recommendations for any type of Pistachio cake? I can drive to LA too if there’s a really good one there
