It's ironic that the latest bar craze is a nostalgic fascination for speakeasies, the hidden drinking holes that flourished during Prohibition. Here in Colorado, we've got the Bitter Bar  in Boulder (which originally functioned as a noodle restaurant by day); Green Russell  in Larimer Square, which is accessed through the Wednesday's Pie  shop; and, open just last week, Williams & Graham  in Highland, which poses as a corner bookstore across from LoHi SteakBar .
When you walk in and give the bookstore clerk your name, she'll write it down and slip it through a crack in the bookshelves. Then, she'll swing open the bookshelves to reveal a pulsing bar scene. The small space has a vibrant 1920s-era feel, from the jazz music playing overhead to the brown leather booths and shiny wall of liquor bottles behind the bar. I swear I even smelled lamp oil.
Try a classic, old-time cocktail like a Moscow mule, old fashioned, or limey daiquiri. (To make it easy, the extensive drink menu is broken down by spirits.) A limited selection of appetizers, entrées, and desserts is also available. I loved the succulent pork terrine, served in a clear glass jar, topped with a creamy layer of fat, and served with several crunchy slices of grilled bread. The deviled eggs were also a nice cocktail companion.
Hint: To snag a conversation-friendly booth, get to Williams & Graham no later than 5:30 p.m.—even on a weeknight.
