What do Italians say when drinking espresso?

Excuse me, but I'm quite intrigued by the cultural nuances surrounding the consumption of espresso in Italy. Could you elaborate on the typical phrase or saying that Italians utter when indulging in this beloved beverage? I've heard whispers of a certain expression that's almost ritualistic in nature, steeped in tradition and passed down through generations of coffee lovers. Is there indeed a specific Italian phrase that accompanies the savoring of an espresso, and if so, what is it? I'd love to gain a deeper appreciation for this custom and its significance within Italian culture.
