Bone up on off-the-menu orders beyond In-N-Out. At the Los Feliz Umami Burger, Smashburgers are available by request. The house-ground meat is slapped on the grill unformed, then charred until the edges are crisp. Follow it up at Hatfield’s, a high-end restaurant where the signature dessert is available only to those who know to ask for it: the chocolate peanut butter truffle cake. (It’s baked to order and topped with salted caramel ice cream and roasted peanut toffee.) For a sweet off-the-menu nightcap, ask for the white peach Bellini at Cecconi’s West Hollywood.
