The selling point of the latest danceteria/party pond complex—atop the Cromwell, right on the edge of the Strip—is that view. But secret weapons abound: the illuminated polyhedron that updates the ol’ disco ball, the abundance of open space and the powerful Funktion-One soundsystem that rattles your innards like the dice inside a Yahtzee shaker. Also: The space is just as attractive as its patrons. Cromwell, 702-777-3800. Nightclub: Tue, Thu-Sun, 10 p.m.-4 a.m.; Beach Club, Fri-Sun, 11 a.m.-6 p.m., cover varies.
