Havana's two biggest dance clubs,
                the Palacio de La Salsa and Ache,
                are in hotels on the waterfront
                promenade known as the Malecon.
                When it was owned by Meyer Lansky
                in the 1950s, the Riviera Hotel
                ballroom that now houses the
                Palacio de La Salsa showcased
                the best of Cuban dance music.
                While much of the hotel decor 
                remains unchanged since before
                the 1959 revolution, the Palacio
                de La Salsa now has a powerful
                set of JBL speakers to blast
                the latest in Cuban salsa.
At private clubs, located far from the waterfront in residential neighborhoods, DJs miraculously pull full dance mixes from the most dilapidated sound systems. When one club changed venue recently, the DJ carried the (3' X 4') speakers on the back of a bicycle.
