Williams & Graham is a prohibition-era speakeasy hidden in a corner bookstore in the Lower Highland neighborhood at 3160 Tejon Street. In true speakeasy fashion, the good stuff is completely hidden behind a bookcase.

To find the bar, you need to pull a copy of Harry Craddock's "The Savoy Cocktail Book" from the shelf, and the bookcase slides open to reveal the hidden bar. The speakeasy features two menus: one with the Williams & Graham team's original creations and another with up to 60 classic cocktails. The bar's impressive library contains more than 500 spirits to draw from, making it a serious destination for anyone who cares about cocktails and drinks history.

Handcrafted cocktails are paired with small plates in an intimate tavern setting. Reservations are a must as this ever-popular Denver institution fills up quickly. There's no standing room, and they never rush anyone out, so plan to settle in for the long haul. Williams & Graham has been recognized by Drinks International's Top 50 Bars in the World list. Come for the hidden entrance, stay for the extraordinary drinks.
