The rebuilding and recovery on the Jersey shore have been prominently reported in the news lately. Jimmy Buffett's Margaritaville Enterprises is making a 35 million dollar investment there. New Jersey Governor Chris Christie cut the ribbon last Thursday at  the 40,000-square-foot Margaritaville Atlantic City. The complex houses  a beach-themed casino, two restaurants, and several bars. There are also several retail stores. Jimmy didn't attend the ribbon cutting. The Atlantic City location is Margaritaville #27.
I recently reported Margaritaville Biloxi didn't have a good first year. Business dropped off rapidly after a hugely successful grand opening. The operation is now under different management, and sweeping changes are in the planning stages.

Margaritaville Enterprises was founded in 2006. The Orlando based company sells everything from beachwear to furniture.
The song  Margaritaville wasn’t a huge hit, peaking at No. 8 on the Billboard 100 charts.  It has however become a hugely lucrative brand.

“If you want to get technical, there are two Margaritavilles. There’s the copyright that protects the song, which is valuable because of the stream of income. Then there’s the trademark that has developed out of the song’s title, and legally that’s a different piece of intellectual property.”

Time will tell if Margaritaville Atlantic City fares better in its first year than Margaritaville Biloxi. It would certainly appear that, as a brand, Margaritaville is alive and well.
