Should a man who wears a beret in a restaurant take it off?

Traditionally, it's considered polite for men to remove their hats, including berets, when dining indoors. This practice stems from etiquette norms that prioritize respect for the dining environment and fellow patrons. However, personal style and cultural significance can also play a role, so it's ultimately a matter of individual choice and context. If unsure, it's generally safer to err on the side of removing the beret.
