Here's What It Means To Receive 'Silent Service' In A Restaurant - Tasting Table
Briefly

Silent service, or royal service, originates from meals served to royalty where discreet signals replaced verbal communication to enhance the dining experience.
In Michelin-starred restaurants, servers strive to anticipate guests' needs through non-verbal communication, allowing diners to focus on their meal and conversation.
Specific non-verbal cues, like tilting your head to signal a waiter or positioning cutlery, enable diners to discreetly communicate with servers throughout their meal.
Non-verbal dining etiquette is often intuitive; observing others in silent service settings can teach diners how to navigate this elegant communication.
