We are having  dinner with the Smiths tomorrow night.

Answer 2

We are going to have dinner with the Smiths tomorrow night.

Answer 3

We are going to have dinner with the Smiths tomorrow night. Would you like to come?

In this sentence, we use "are going to" to talk about a planned future event. It indicates that the action of having dinner with the Smiths is already arranged and scheduled to happen in the future.

The use of "are going to" implies that the speaker has already made plans with the Smiths to have dinner together. It suggests that the speaker and the Smiths have agreed on the time and place for the dinner.

The invitation "Would you like to come?" is in the present simple tense. It is a polite way of asking if the person being addressed would be interested in joining the speaker for dinner with the Smiths.

Overall, this sentence is a combination of present continuous ("are going to") and present simple ("Would you like to come?") to express a planned future event and extend an invitation.
