Rey Castro, LANúS

Spend enough time in Buenos Aires and the inescapable tango just might start to wear on you. Don't feel guilty, just do like the locals and head over to San Telmo's Cuban resto-bar and discotheque, Rey Castro, which features a Caribbean menu, dinner shows, and all-night dancing on its three levels in this renovated antique garage. The food isn't anything to write home about, nor are the dinner shows, but the happy hour specials invite you to enjoy gigantic two-for-one mojitos at the sprawling, perpetually crowded bar or at a shaky wooden table under the atmospheric arched brick ceilings. If the mood strikes you, stay and dance until 5am like a true porteno. - Elizabeth Gleeson
