Voy al puesto de tacos después del trabajo.

In Spanish, the subject pronoun is often omitted because the verb ending already tells you who the subject is.

• Voy = I go / I’m going
• The -oy ending tells you it is yo

So Voy al puesto de tacos... is completely natural.
You could say Yo voy..., but that usually adds emphasis, contrast, or clarity.

For example:

• Voy al puesto de tacos. = neutral
• Yo voy al puesto de tacos, pero él no. = I am going, but he isn’t

Because a + el contracts into al in Spanish.

• a = to
• el = the
• a el → al

So:

• Voy al puesto = I’m going to the stand

This contraction is required in normal Spanish.

A similar rule appears later in the sentence:

• de + el → del

Puesto usually means a stand, stall, or small food-selling spot, often informal or street-based.

So puesto de tacos is:

• a taco stand
• a taco stall
• a small place selling tacos

The structure noun + de + noun is very common in Spanish for this kind of idea:

• puesto de tacos = taco stand
• tienda de ropa = clothing store
• jugo de naranja = orange juice

Here, de tacos means something like for tacos / that sells tacos.

Spanish often uses de + noun without an article when describing the type or purpose of something.

So:

• puesto de tacos = taco stand
• puesto de flores = flower stand
• tienda de zapatos = shoe store

Adding los would make it sound more specific, as if you were talking about particular tacos already known in the conversation. In this sentence, the meaning is general: it’s a stand that sells tacos.

Because de + el contracts into del.

• después de = after
• el trabajo = work
• después de el trabajo → después del trabajo

So:

• después del trabajo = after work / after the workday

This contraction is also standard and expected.

Spanish often uses the definite article where English does not.

So even though English says:

• after work

Spanish naturally says:

• después del trabajo

This doesn’t necessarily mean after the specific work in a very literal way. It’s just the normal Spanish structure.

You’ll see this often:

• Voy a la escuela. = I go to school
• Me duele la cabeza. = My head hurts / I have a headache
• Después del trabajo = after work

Grammatically, voy is present tense:

• voy = I go / I am going

But in Spanish, the present tense is very often used to talk about near-future actions, especially when the context makes the time clear.

So this sentence can mean something like:

• I’m going to the taco stand after work
• I go to the taco stand after work
• I’m going to go to the taco stand after work

Because después del trabajo gives a time reference, using the present sounds natural.

Yes. That is also correct.

• Voy al puesto de tacos... = more direct, very natural
• Voy a ir al puesto de tacos... = literally I am going to go..., a more explicit future

In everyday Spanish, both can work.
Very often, speakers prefer the simpler Voy... when the future is already clear from context.

That word order is the most natural and neutral here.

Spanish often places time expressions like this at the end:

• Voy al puesto de tacos después del trabajo.

But you can move it for emphasis:

• Después del trabajo, voy al puesto de tacos.

Both are correct. The original version just sounds smooth and standard.

A simple pronunciation guide:

• voy ≈ boy with a softer b/v sound
• puesto ≈ PWEHS-toh
• después ≈ dehs-PWEHS

A few helpful notes:

• ue in puesto often sounds like we
• The accent mark in después shows the stress goes on the last syllable: -pués
• In most Latin American Spanish, v and b sound very similar

The infinitive is ir, which means to go.

Voy is the yo form of ir in the present tense.

Present tense of ir:

• yo voy = I go
• tú vas = you go
• él/ella/usted va = he/she/you go
• nosotros vamos = we go
• ustedes van = you all go
• ellos/ellas van = they go

It is an irregular verb, so its forms do not follow the usual patterns.

It fits very well in a Latin American context, especially because taco stands are strongly associated with Mexico and nearby regions.

That said, the word puesto itself is common broadly in Spanish and can mean:

• stand
• stall
• booth
• post/position, depending on context

In this sentence, the food-stand meaning is clear.
A native speaker in Latin America would understand it naturally.
