What does que bueno mean?

"Que bueno" in Spanish means "How good!" or "That's good!" It's a common expression of approval, similar to saying "Good!" or "Nice!" in English.

It can be used in various contexts, for example:

* Expressing appreciation: "Que bueno que viniste!" (How good that you came!)

* Reacting to good news: "Que bueno que te sientes mejor!" (That's good that you're feeling better!)

* Commenting on something enjoyable: "Que bueno está el café!" (This coffee is so good!)

The literal translation is "How good," but it's typically used as a more concise and informal way to express approval.
