The Best Espresso Martinis in Las Vegas | Eater Vegas

"The Waldorf Astoria is always topping its own luxury bar offerings, and the reimagined Hard Shake brings an inventive cocktail list that won’t be forgotten anytime soon. The former Skybar now invites visitors into a dark and romantic Art Deco interior, perfect for enjoying strong and caffeinated martinis. Buckle in for a Bullet Train, an amped-up blend of reposado tequila, espresso concentrate, espresso liqueur, and a sweet dash of Angostura cocoa bitters to complement the agave. Gold chocolate coffee beans garnish a rocks glass, making for an elegant presentation." - Jennifer Smith
