It has world-class buffets and some of the best shopping in the country; it's got Celine and Tina, not to mention Cher and Bette. It can be seen from space. Las Vegas -- every year it gets bigger and better than ever. That's why we're showing you the hottest attractions right now -- 1 phenomenally sexy place for every year that makes you legal. It's the City of Sin, and we're taking you to the 21 hottest locations on the Vegas Strip.

No. 21: Cathouse
Luxor
Sexy and sophisticated, Cathouse is all about enticement. Drawing inspiration from the bordellos of 19th-century Europe, the cuisine from famed chef Kerry Simons tempts your palate, while the lingerie-clad dancers and European-style bottle service challenge your inhibitions.

No. 20: Mandalay Bay Beach
Mandalay Bay
The best Las Vegas daytime hot spots offer opulent refuges from the heat. Located on 11 acres of sand and surf, Mandalay Bay Beach is the height of Vegas's aquatic indulgence. Boasting a wave pool, lazy river, three swimming pools, and private cabanas and bungalows, there's something to satisfy every sunbather.

No. 19: Jonathan Adler Megasuite
Planet Hollywood Resort
If you're up on the tables (and we mean way up), why not mega-treat yourself to Jonathan Adler's megasuite? Located in the heart of the Vegas Strip at the ultra-modern and ultra-chic Planet Hollywood resort, this suite has more amenities than Vegas has showgirls, including panoramic views of the Strip. And it's all styled by Bravo's Top Design lead judge, Jonathan Adler. In short, this megasuite is mega-sweet.

No. 18: Tao
The Venetian
Tao at The Venetian is the perfect combination of clubbing and cuisine. Begin your Tao experience by feasting on the Pan-Asian cuisine before heading upstairs to 1 of the hottest clubs in the country. The atmosphere at Tao is dominated by the DJ, who pumps music through 2 main dance rooms and one 40-foot-long outdoor terrace with stunning Vegas views. Take one step inside Tao, and you'll see that entertainment is their philosophy.

No. 17: Rao's
Caesars Palace
The famed New York-based restaurant has staked its claim on the Strip. If you're looking for a simple home-cooked Italian meal, look no further than the Rao's menu, featuring their renowned pastas, risottos and steak bistecca. In the fall and winter months, enjoy al fresco dining with the warmest of service.

No. 16: Bare Pool
Mirage
The name Bare is certainly not a nod to provisions of the bare necessities. Instead, VIP service is the norm at Bare, their daybed and cabana services offering iced towels, rolled and chilled in flavored water; exotic frozen fruit; icy popsicles, and mini fruit smoothies. With amenities like those, the only thing you'll have to skimp on is clothing -- guests at Bare enjoy European-style sun bathing.

No. 15: Wynn Esplanade
Wynn Las Vegas
If you're looking for a daytime activity out of the desert sun, take a trip to the Wynn Esplanade. The store directory reads like a Who's Who of Fashion -- Dior, Chanel, Louis Vuitton, Oscar de la Renta, and Manolo Blahnik, just to name a few.

No. 14: Moon
The Palms
While other nightclubs on the Strip may be celebrity favorites, Moon is the only one that can promise star sightings every night. That's because in the main room at Moon, the roof is completely retractable. When closed, the roof acts as a large video screen on which the action from all over the club is projected. The floor is made of shimmering tiles that change color via a high-tech lighting system. If you're looking to be dazzled on your trip to Vegas, landing at Moon should be the first step you take.

No. 13: Ivan Kane's Forty Deuce
Mandalay Bay
On the surface, Ivan Kane's Forty Deuce is a burlesque lounge with an old-fashioned Las Vegas feel. However, as is the case in Sin City, there's more here than meets the eye. At showtime, the circular back bar vanishes, the band appears and the paintings of nudes adorning the walls retract, so even more people can see the show. When the show is over, the DJ takes over, and there's dancing till dawn.

No. 12: Red Rock Lanes
Red Rock Casino Resort
Does all this hot action leave you wishing for a little serenity now? No problem. Take a quick break from the sizzling Strip and head to Red Rock Casino Resort and Spa. Tranquil and luxurious surroundings provide a level of relaxation that's beyond your dreams. If you're still in the mood to play, then choose from concerts, nightclubs, bars, movie theaters and one of the most decadent bowling alleys ever designed. Red Rock is sure to please, no matter what your party style.

No. 11: Prive
Planet Hollywood Resort
If you're looking to party like a Hollywood A-lister -- or better yet, with a Hollywood A-lister -- then you'll want to find yourself on the other side of Prive's velvet rope. To be a VIP (very important Prive), you simply need to dress to impress and be ready to pay a Vegas-sized bar tab.

No. 10: Hard Rock Beach Club
Hard Rock Hotel and Casino
Cerulean-blue water winds almost a mile while caressing soft sand beaches. The sounds of a nearby waterfall drift lazily to your thatched-roof cabana. No, you're not in the Caribbean, you're at the Hard Rock Beach Club. This is Vegas though, and that means zen comes served on the rocks. This oasis is also home to one of the most kickin' pool parties in the world, so get there early for a prime spot in the fun and sun.

No. 9: Strip House
Planet Hollywood Resort
The next spot on this scintillatingly sinful countdown brings us just above the casino floor at the Planet Hollywood Resort to the Strip House. Indulge your carnal fantasies with strips, mignons or bone-in rib eyes.

No. 8: Box Waxing Boutique
With so many numbers on our countdown including words like, "bare," "strip" and "lingerie," its no wonder that  Box Waxing Boutique is on the list. In fact, glance back through this list, and you may want to make number 8 your number-1 priority.

No. 7: Gaming Floor
Hard Rock Hotel and Casino
Nothing pairs with rock 'n' roll like gambling (well, maybe there's one or two other things), and that's evident the moment you enter the Hard Rock Hotel and Casino's gaming floor. Of course, there's blackjack, roulette, craps and poker, but no one kicks it up a notch like the Hard Rock. Check out the one-of-a-kind poker lounge, the race and sportsbook lounge to bet on all your favorite teams, and the High Limit room, whose name speaks for itself.

No. 6: Tryst & Blush
Wynn Las Vegas
Tryst and Blush, both located at the Wynn Las Vegas epitomize the seductive extravagance of the Las Vegas lounge and nightclub. Tryst is home to a breathtaking 90-foot waterfall visible from the dance floor. Blush is more understated and intimate, overlooking the casino and characterized by its onyx dance floor. With these two choices, it's a Wynn-Wynn situation.

No. 5: Hugh Hefner Sky Villa
Palms Casino Resort
If you've got plenty of cash and plenty of friends, then there's only one place to host the ultimate Las Vegas house party, the Hugh Hefner Sky Villa at the Palms Casino Resort. The glass elevator, 8-foot-round rotating bed and outdoor, cantilevered Playboy Jacuzzi pool are just a few examples of this premier suite's opulence.

No. 4: Crazy Horse Paris
MGM Grand
 The Crazy Horse Paris Cabaret is Las Vegas's definitive dedication to the female form. The 13 dancers in this seductive revue all trained with the original Crazy Horse dance troupe in Paris. Sensuous dancing is combined with artistic light displays and films to create an artistically erotic experience.

No. 3: Pussycat Dolls Lounge
Caesars Palace
In their latest hit single, the Pussycat Dolls warn, "be careful what you wish for, cuz you just might get it." A warning that befits visiting the Pussycat Dolls Lounge at Caesars Palace -- the girls are so hot, the dancing so sexy and the scene so smoking, it might leave you thinking you wished for too much from just one club.

No. 2: Wet Republic
MGM Grand
 The Wet Republic pool at the MGM Grand combines the thrill of the Vegas nightlife with the luxury of the Vegas day scene. With 2 spectacular saltwater pools, 8 individual pools and spas, exclusive VIP Bungalows, hip party cabanas and daybeds, Wet Republic has a poolside niche for everyone. For those seeking more than a suntan, there's a 2,500-square-foot lounge that's kicking the scene all day, every day.

No. 1: Playboy Club
Palms Casino Resort
 The Playboy Club at the Palms Casino Resort is the answer to all your vices. Fantasy truly does meet reality at this one-of-a-kind adult playground. Bunnies deal the cards in these high-stake games, and face it, when Hefner's involved, you know you're getting the red-carpet treatment.
