The best option for the meaning of the expression is: a private conversation.

The French expression "tête-à-tête" means precisely that: a private conversation that usually takes place between two people. It could also involve more people as long as it's still intimate. This expression literally means "head-to-head", since the word tête comes from Old Frech teste (head.).
