What does Quisiera usted salir conmigo mean?

"Quisiera usted salir conmigo" is a formal way of asking someone out on a date in Spanish.

It literally translates to "I would like you to go out with me", but a more natural English translation would be:

"Would you like to go out with me?"

This is a polite and respectful way to ask, but it's important to note that it's quite formal. It's more common to use a less formal phrase in everyday conversation.
