Nikki Beach, Miami
This beach bar is where you can mingle with South Florida's “beautiful people.” An open-air space with daybeds, Miami's Nikki has a strict door policy. This place looks and feels (and acts) like it belongs on the French Riviera, but it's right on Ocean Drive.
This place is cool, but it's actually a chain. There are Nikkis in Morocco and Cabo San Lucas and on the Thai island of Koh Samui. DJs spin at night, turning the upscale chill-out venue into an upscale party venue. You'll probably need a reservation if you want to get in the door at any time of day or night. If you're visiting the Miami Beach/South Beach area, this is something your hotel concierge could probably arrange for you.
