¿Te viene bien ir al festival de cine del barrio el viernes por la tarde?

Venir bien is a very common expression meaning to suit someone, to be convenient, or to work well for someone.

So te viene bien means something like:

• Does it suit you?
• Is it convenient for you?
• Does that work for you?

You should learn venir bien as a fixed expression, because the literal idea of come well is not how English would normally say it.

Because te is not the subject.

In this sentence, the subject is the whole action:

ir al festival de cine del barrio el viernes por la tarde

That whole infinitive phrase acts like going to the neighborhood film festival on Friday afternoon.

Since an infinitive phrase is treated as singular, the verb stays in third-person singular:

• Te viene bien ir...

Not vienes, because the sentence is not saying you come.

Yes. Te va bien is also very natural.

Both te viene bien and te va bien can mean Does that work for you?

A rough difference is:

• te viene bien = is it convenient / does it suit you?
• te va bien = does it work for you?

In everyday conversation, both are common and often interchangeable.

Because Spanish often uses an infinitive to talk about an action in a general way.

Here, ir al festival... means going to the festival...

It works as the thing being evaluated:

• Me viene bien salir temprano = Leaving early suits me
• Nos viene bien quedar mañana = Meeting tomorrow works for us

So in your sentence, ir al festival... is the action that may or may not be convenient.

Because a + el contracts to al in Spanish.

So:

• a el festival → al festival

This contraction is standard and expected.

The same happens with:

• de + el → del

That is why you also see del barrio later in the sentence.

They are doing two different jobs:

• festival de cine = film festival
• del barrio = of the neighborhood / in the neighborhood / local

So the full phrase means something like:

• the neighborhood film festival
• the local film festival

De cine tells you what kind of festival it is.
Del barrio tells you which festival.

In Spanish, days of the week often take the definite article:

• el lunes
• el viernes
• el sábado

So el viernes means on Friday.

English uses on, but Spanish usually does not. Instead, it uses the article.

In context, el viernes normally means a specific Friday, often this Friday or Friday as understood from the conversation.

In Spain, the normal expression is por la tarde for in the afternoon.

Similarly:

• por la mañana = in the morning
• por la noche = in the evening / at night

En la tarde does exist, but it is less common in Spain and more common in some parts of Latin America. For Spain-focused Spanish, por la tarde is the form you should expect most often.

Yes. Te is the indirect object pronoun used with tú, so this sentence is informal and addressed to one person.

Compare:

• ¿Te viene bien...? = informal singular
• ¿Le viene bien...? = formal singular
• ¿Os viene bien...? = informal plural in Spain
• ¿Les viene bien...? = formal plural, or plural in many Latin American varieties

So this sentence sounds like you are speaking casually to one person.

Because Spanish uses inverted question marks.

A direct question is written with:

• ¿ at the beginning
• ? at the end

So:

• ¿Te viene bien ir...?

This helps the reader know from the start that the sentence is a question.

Yes. Spanish word order is more flexible than English word order.

You could also say:

• ¿Ir al festival de cine del barrio el viernes por la tarde te viene bien?

That is grammatical, but ¿Te viene bien ir...? sounds more natural and conversational because it puts the key question first.

Spanish often moves parts of the sentence around for rhythm, focus, or style.

Here, cine means film or cinema in the sense of movies as an art form, so festival de cine is a film festival.

In other contexts in Spain, cine can also mean movie theater:

• Vamos al cine = Let’s go to the cinema / Let’s go to the movies

So the exact meaning depends on context. In this sentence, it clearly means film.
