Las Vegas history is on glorious display in this reinvention of a classic watering hole. The building dates back to 1945 and is the oldest freestanding bar in the city. It got its name in 1952 when people used to go up on the roof to watch the aboveground nuclear blasts from the Atomic Test Site north of Las Vegas and became a go-to spot for everyone from the Rat Pack to Barbra Streisand, who has her own memorial stool at the bar. Now fully restored after years of decline, there’s a classic neon sign out front and a big bar and plenty of comfy seating inside, plus nearly two dozen microbrews, a craft cocktail menu (featuring some classic “Atomic” concoctions), and a variety of events to keep things interesting. It recently added on a dining addition called The Kitchen at Atomic, for great bar bites to go along with your beverages. One note: This is one Vegas bar that is not open 24 hours. Atomic Liquors is open Monday through Wednesday from 4pm until 2am; Thursday from 2pm until 3am, Friday from 2pm until 4am; Saturday from noon until 4am; and Sunday from noon until 2am.
