For casino action in the town itself, head for the previously recommended Matum Hotel & Casino. Its Casino Diamante spins all night, and is very evocative of certain joints in Las Vegas. Also on-site is the Laao Club, open nightly 7pm to 2am, with live music often presented. For a more elegant casino, head out to the also-recommended Hodelpa Gran Almirante.
For the best merengue and dancing in Santiago, the place to go is Tipico Monte Bar, Avenida 27 de Febrero 18 (tel. 809/575-0300; www.tipicomontebar.com), open nightly except Tuesday from 5pm to 3am (or even later, depending on the crowd). Live music is often a feature, as some of the best singing groups in the Caribbean emerge from Santiago. The location is a RD$105 taxi ride from the center; the club is in the Las Colinas sector, with all its car-repair shops.
One of the city's most popular bars is Ali-Bar, at the corner of Calle Tolentino and Avenida Restauración (tel. 809/581-6779; www.ahi-bar.com), open nightly from 4pm to 2, 3, or even 4am. It opens onto a big courtyard. Food is served here, and outdoor jazz is often featured.
