Plumes of fine cigar smoke hang in the air. A pair of pudgy dudes dressed in guayaberas and khaki shorts puff on premium stogies. Near the entrance of Guantanamera Cigars, a raven-haired woman in a sequin one-piece bathing suit and a Carnival headdress sashays inside, where a crowd packs the small dance floor. Afro 23 is banging out a set that blends salsa and pop beats as revelers knock back mojitos or shots of Cuban rum. Located in the heart of Little Havana, Guantanamera is an intimate live music venue reminiscent of a pre-Castro Havana watering hole. The lineup changes throughout the weekend, with a rotation of unheralded salsa, merengue and reggaeton artists from the Caribbean who play for the sheer excitement of performing for a live audience. Guantanamera opens its doors every day at 10:30 a.m. Closing time is at 9 p.m. Monday through Wednesday, midnight on Thursday and Sunday, and 3 a.m. Friday and Saturday.
