DEEP BACKGROUND: Set within a real cave, complete with stalactites and a batty atmosphere, this good-time grotto doubles as a subterranean disco. Seventy-five steps descend 60 feet into the earth's bowels, where you'll find three dance floors and seating for up to 3,000 guests.
CAST OF CHARACTERS: The action takes place on weekends when the club is packed with European and South American tourists. Busloads of ready-to-party guests arrive after 11 p.m. and hang around into the wee hours of the morning. While locals do frequent the place - often renting the cave for special occasions - the feel is decidedly international.
SUSTENANCE: Don't expect to find those supersweet, you're-on-vacation concoctions with umbrellas here. Most just go for beer - Presidente is a favorite - or rum and Coke, with local rum. Snacks include pig leg sandwiches (slices of pork, veggies and mild spices stir-fried and wrapped in a flat bread).
DIVERSIONS: Deejays are the norm, but a live band mixes it up once a month. Music ranges from Dominican merengue to international pop along the lines of Ricky Martin. As if being in a cave isn't scary enough, disco lighting gives the place a slight Saturday Night Fever ambience. During the high season, guests enjoy a one-hour folkloric show on Friday nights.
LOCAL KNOWLEDGE: The club is situated within Parque Mirador Sur, nicknamed "health park" because of the countless joggers and in-line skaters who flock there. Between 4 p.m. and 7 p.m., the thoroughfare leading to the club is closed to car traffic so fitness buffs can have their run of the road.
