The entire city stretches out beneath Fifty Ultra Lounge. Fifty stories high, atop the tower that houses the Viceroy hotel, a swimming pool glitters under the sun or moon. Around it, partiers rock to the beats of the city's top DJs or simply share their cocktails with the panoramic views: the skyline on one side and the ocean on the other. Inside, grained marble, fresh flowers, and Japanese woodblock prints make for an elegant space to share champagne and help distinguish the club from an upscale pigeon roost.
