A mi novio y a mí nos apetece brindar después de la última película, siempre que no salgamos demasiado tarde.

Because Spanish often marks the people affected by verbs like gustar and apetecer with an indirect object phrase introduced by a.

So:

• A mi novio y a mí = to my boyfriend and me
• nos apetece = appeals to us / we feel like

Together, that structure means something like:

• To my boyfriend and me, it feels appealing to make a toast
• more naturally: My boyfriend and I feel like making a toast

This a + person phrase is very common with verbs like:

• gustar
• encantar
• interesar
• apetecer

It helps clarify who is experiencing the feeling.

Because after a preposition like a, Spanish uses prepositional pronouns, not subject pronouns.

So:

• yo = I (subject form)
• mí = me (used after prepositions)

That is why you say:

• a mí = to me
• not a yo

Compare:

• Yo estudio español. = I study Spanish.
• A mí me gusta el español. = Spanish is pleasing to me / I like Spanish.

Yes, it is a kind of repetition, but it is very normal in Spanish. This is called clitic doubling.

In sentences like this, Spanish often uses:

1. the full phrase: A mi novio y a mí
2. and the indirect object pronoun: nos

So:

• A mi novio y a mí nos apetece...

This is standard and natural. The pronoun nos is not optional here in normal usage.

A rough parallel in English would be something like:

• As for my boyfriend and me, we feel like...

Spanish just does this much more regularly.

Because the thing that is grammatically doing the verb is brindar, and an infinitive counts as singular.

Think of it this way:

• Nos apetece brindar.
• Literally: Making a toast appeals to us.

Since brindar is one action, the verb is singular:

• apetece ✅

Compare:

• Nos apetece brindar. = We feel like making a toast.
• Nos apetecen unas copas. = We feel like some drinks.

In the second example, unas copas is plural, so the verb becomes apetecen.

Apetecer is often used for feeling like something, especially in the moment. It works a lot like gustar.

So:

• Me apetece salir. = I feel like going out.
• Nos apetece brindar. = We feel like making a toast.

Compared with querer:

• Quiero salir. = I want to go out.
• Me apetece salir. = I feel like going out.

The difference is often:

• querer = want, desire
• apetecer = feel like, be in the mood for

In Spain, apetecer is very common in everyday speech.

Brindar usually means to make a toast or to drink to something/someone.

Examples:

• Brindar por algo = to toast something
• Brindar por vosotros = to drink a toast to you

In this sentence, brindar most naturally suggests:

• having a celebratory drink
• making a toast after the movie

In Spain, this sounds natural in a social context.

Because después normally needs de before a noun.

So:

• después de la película = after the movie
• después de cenar = after dinner / after eating dinner

You usually need de after después unless después is being used on its own:

• Primero cenamos y después salimos. = First we have dinner and afterwards we go out.

But before a noun phrase like la última película, use:

• después de...

It can mean either, depending on context.

• la última película can mean the last movie in a sequence
• or the latest movie

In this sentence, if there is a series of films or a movie marathon, it may mean the last film. In another context, it could mean the latest movie.

Spanish often leaves that to context, just like English sometimes does.

Also notice the adjective order:

• la última película is the normal order in Spanish
• noun-adjective order is very common: película interesante, día largo, etc.

It can, but here it means provided that or as long as.

Siempre que has two common uses:

1. whenever

   • Siempre que lo veo, me saluda.
   • Whenever I see him, he says hello.

2. provided that / as long as

   • Iré, siempre que tenga tiempo.
   • I’ll go, as long as I have time.

In your sentence, it clearly has the second meaning:

• siempre que no salgamos demasiado tarde
• as long as we don’t leave too late

Because siempre que meaning provided that / as long as usually requires the subjunctive when referring to a condition or something not yet confirmed.

So:

• siempre que no salgamos demasiado tarde = as long as we don’t leave too late

Here, leaving late is a future possibility, not a known fact. That is why Spanish uses the present subjunctive:

• salgamos

This comes from the verb salir:

• yo salga
• tú salgas
• él/ella salga
• nosotros salgamos
• vosotros salgáis
• ellos salgan

Because the condition is negative:

• provided that we do not leave too late
• as long as we don’t leave too late

So:

• siempre que salgamos tarde = as long as we leave late
• siempre que no salgamos tarde = as long as we do not leave late

The no simply negates the verb.

It means too late.

• tarde = late
• demasiado = too / excessively

So:

• salir demasiado tarde = to leave too late

Compare:

• muy tarde = very late
• demasiado tarde = too late

That difference matters:

• muy tarde just describes a late time
• demasiado tarde suggests it is later than is acceptable or convenient

Not in the same structure.

You could say:

• Mi novio y yo queremos brindar...
• My boyfriend and I want to make a toast...

But with apetecer, the natural structure is:

• A mi novio y a mí nos apetece...

That is because apetecer does not work like querer. It works more like gustar, where the experiencer is expressed as an indirect object.

So:

• Mi novio y yo queremos... ✅
• A mi novio y a mí nos apetece... ✅
• Mi novio y yo apetecemos... ❌ in this meaning

It sounds especially natural in Spain because apetecer is very common there in everyday speech.

A speaker from Spain would very naturally say things like:

• Me apetece un café.
• ¿Os apetece salir?
• No nos apetece quedarnos en casa.

In many parts of Latin America, people may understand it perfectly, but they might more often use other expressions, such as:

• tener ganas de
• querer
• se me antoja in some regions

So the sentence is fully correct Spanish, and it has a distinctly natural Spain feel.

Yes:

• A mi novio y a mí = to my boyfriend and me
• nos = to us
• apetece = is appealing / we feel like
• brindar = making a toast / to toast
• después de = after
• la última película = the last/latest movie
• siempre que = as long as / provided that
• no salgamos = we don’t leave
• demasiado tarde = too late

A very literal structure would be:

• To my boyfriend and me, making a toast is appealing after the last movie, provided that we don’t leave too late.

A natural English version would be:

• My boyfriend and I feel like making a toast after the last movie, as long as we don’t leave too late.
