Formal:
* Le thé de l'après-midi: This is the most literal translation and is appropriate for formal settings.
* Le goûter: This literally means "snack," but it's often used to refer to a light meal in the afternoon, which could include tea and pastries.
Informal:
* Le thé: This is simply "tea" and can be used in informal contexts where the context makes it clear you're referring to afternoon tea.
* Un thé gourmand: This means "a gourmet tea" and emphasizes the pastries and treats served.
Other options:
* Le thé à l'anglaise: This translates to "English tea" and is a specific type of afternoon tea.
* Le thé de cinq heures: This means "five o'clock tea" and is another way to refer to afternoon tea.
The best choice will depend on the situation and your desired level of formality.
