To make your trip to Las Vegas memorable, we did a little sleuthing. Try these unusual spots!

Ghost busters: Haunted Vegas Tour and Ghost Hunt buses guests to some of the most haunted locations in the city. Armed with equipment used by paranormal investigators, you’ll visit places such as the “Motel of Death,” where numerous celebrities expired over the years, and Liberace’s haunted dressing room.

Blast from the past: Atomic Liquors is a little bar and store with a big history. Once a hangout for mobsters and performers such as Frank Sinatra and Dean Martin, it was also where locals went to watch government testing of nuclear bombs. In the 1950s and ‘60s, patrons went up to the roof with their libations to watch the desert sky light up. The landmark was closed in 2010; the new owners reopened it late last year. Check out the “bar-seum” and potent drinks. Open Wed.-Sun. and late nights; 917 Fremont St., Las Vegas; (702) 982-3000.

Burlesque beauties: Burlesque is alive and well in Sin City – in classic or “adult” versions.

Hipster hangout: The Velveteen Rabbit in the Arts District is a cocktail lounge with a trendy vibe.

Did someone say “zombies”? The Zombie Apocalypse Store located in Chinatown, has been described as having “a fantastical cornucopia of all you’ll ever need to survive when the shizz hits the fan.” From swords and axes, camping gear and foodstuffs to zombie training dummies (yeah, we looked that up, and they’re manikins you can practice on in preparation for a zombie invasion). Open 9 a.m.-9p.m.; 3420 Spring Mountain Rd., Las Vegas; (866) 784-7882.

Cool cars: It’s been called “the world’s largest classic car showroom,” and the Auto Collections at The Quad Resort & Casino (formerly the Imperial Palace) is an auto aficionado’s dream come true.

Mmm: Decisions, decisions – raspberry or coconut M&Ms? Purple or teal? M&M’s World has flavors and colors you won’t find in the local grocery store.
