If there’s one night to slide into a booth at this casual diner inside the hip Ace Hotel & Swim Club, make it a Monday. That’s when the place is transformed by the unmissable presence of 90-year-old ex-showgirl Shirley Claire, who sings and brings a healthy dose of razzle-dazzle as she hosts Fabulous Bingo. In fact, most nights of the week have a theme—see Tuesday karaoke at the adjacent Amigo Room bar, half-off wine bottles on Wednesday, and Taco Jueves—so making reservations is a good idea, but not a must. If you wind up waiting for a table, grab an Orange You Glad To See Me—made with gin, orange, Chareau, and lime—and pop into the photo booth. With its stone wall, leather booths, and globe pendant lights, the diner (a former Denny’s) embraces the spirit of the sixties, while the menu offers a distinctly Californian twist on Southwestern and Mexican fare. Must-orders: For breakfast (served until 2 p.m.), opt for the desert classic Date Shake and Huevos Rancheros, made with California- and Coachella Valley–sourced ingredients. For dinner, try the Grilled Mahi Mahi Tacos or Desert Highway Burgers, and request the pickled jalapeños for added kick.
