"It's clear from the moment you walk in that Del Diego is a Madrid institution—one that would make a primo Wolf of Wall Street shooting location with its louche, New York-circa-1990 swagger. Every evening, suit-and-tie regulars (and culture-seeking tourists) congregate at the glossy wooden bar to sip Martinis and white Russians with reckless abandon. Bring your boss here and let the company pick up the tab, or settle in late-night for a dram of whiskey and an impromptu barside chat." - Benjamin Kemper
