Por mucho que me canse el sol, sé que acabaré por volver a este chiringuito porque aquí se cena muy bien.

Por mucho que is a concessive expression. It means something like:

• no matter how much
• however much
• even if ... a lot

In this sentence, Por mucho que me canse el sol means:

• No matter how much the sun tires me
• However tiring the sun is for me

It introduces an idea that does not stop the main action in the sentence. So even though the sun may be exhausting, the speaker still says they will come back.

A very common pattern is:

• Por mucho que + subjunctive

Examples:

• Por mucho que estudies, siempre habrá algo más que aprender.
• Por mucho que lo intente, no puedo olvidarlo.

So here, it sets up a kind of “despite that” idea.

Because por mucho que normally triggers the subjunctive.

So:

• cansa = indicative
• canse = subjunctive

After concessive expressions like por mucho que, Spanish often uses the subjunctive because the speaker is not simply stating a neutral fact. They are presenting something as a circumstance that does not change the outcome.

So:

• Por mucho que me canse el sol... = No matter how much the sun tires me...

This is the standard structure.

You can think of it like this:

• Sé que acabaré por volver... = the speaker is sure about returning
• Por mucho que me canse el sol... = the tiring effect of the sun is treated as a competing factor, but it does not matter in the end

That is why the subjunctive fits naturally here.

Because cansar can mean to tire someone / to make someone tired.

So in:

• me canse el sol

the parts are:

• me = me / to me in the sense of the affected person
• el sol = the sun (the thing causing the tiredness)
• canse = tires

So literally it is:

• the sun tires me

This is very common in Spanish with verbs that affect a person:

• Me preocupa el examen. = The exam worries me.
• Me molesta el ruido. = The noise bothers me.
• Me cansa el calor. = The heat tires me.

English learners sometimes expect the person to be the grammatical subject, but in Spanish the thing causing the feeling is often the subject.

Because Spanish word order is more flexible than English, especially when the sentence already has an object pronoun like me.

Both of these are possible:

• Por mucho que el sol me canse...
• Por mucho que me canse el sol...

The version in your sentence sounds very natural. Putting el sol after the verb can make the sentence flow better and keeps the focus first on me canse.

This kind of order is common in Spanish, especially when:

• the subject is already clear from context
• the speaker wants a smoother rhythm
• the subject is not the main focus

So me canse el sol is not strange at all; it is just a very natural Spanish ordering.

Acabar por + infinitive means something like:

• to end up doing something
• to eventually do something
• to wind up doing something

So:

• acabaré por volver = I’ll end up coming back / I’ll eventually come back

This is slightly different from just volveré:

• volveré = I will come back
• acabaré por volver = I’ll end up coming back, often after some resistance, hesitation, or delay

That nuance matters here. The sentence suggests:

• the sun wears the speaker out
• even so, they know that in the end they will return

So acabaré por volver gives a sense of final inevitability.

Other examples:

• Al final acabó por aceptar la oferta. = In the end, he ended up accepting the offer.
• Acabarás por entenderlo. = You’ll eventually understand it.

Because acabar por + infinitive is a fixed verbal structure in Spanish.

It does not mean finish by in a literal word-for-word sense. You should learn it as a chunk:

• acabar por hacer algo = to end up doing something

Examples:

• Acabó por rendirse. = He ended up giving up.
• Acabaron por mudarse. = They eventually moved.

So in your sentence:

• acabaré por volver = I’ll end up coming back

You generally cannot remove the por if you want this specific meaning.

In Spain, a chiringuito is typically a casual bar or small restaurant, often:

• by the beach
• outdoors or semi-open-air
• informal
• serving drinks and food

It is a very culturally Spanish word, especially associated with seaside places.

So este chiringuito gives a very specific feel: not just any restaurant, but a relaxed, probably coastal spot where people eat and drink, especially in summer.

Depending on context, translating it simply as beach bar or beachside restaurant may work, but chiringuito has a strong local flavor that English does not capture perfectly.

This is an example of impersonal se.

• cenar = to have dinner
• se cena = literally something like one dines / people have dinner

So:

• Aquí se cena muy bien = You eat very well here / People have dinner very well here / more naturally, The food here is very good for dinner or You can have a very good dinner here

The important grammatical point is that se makes the sentence impersonal. It does not refer to a specific person. It means people in general.

Very common examples:

• Aquí se vive bien. = Life is good here / People live well here
• En España se cena tarde. = In Spain people eat dinner late
• Se habla español aquí. = Spanish is spoken here

In your sentence, se cena muy bien is a very natural Spanish way to praise a place.

Because this is impersonal se, not a true passive with a plural subject.

In se cena muy bien:

• there is no expressed subject
• cena stays in third person singular

It means people dine / one dines.

Compare:

• Aquí se cena muy bien. = impersonal, People eat dinner very well here
• Aquí se sirven buenos platos. = passive-like, Good dishes are served here

In the second sentence, buenos platos is a plural subject, so the verb becomes sirven.

But with se cena, there is no subject like that, so singular cena is correct.

Because cenar specifically means to have dinner / to eat the evening meal.

Spanish distinguishes clearly between:

• desayunar = to have breakfast
• comer = to eat / to have lunch or the main meal
• cenar = to have dinner

So aquí se cena muy bien means the place is especially good for dinner, not just for food in general.

This also fits the cultural setting of a chiringuito, since many people in Spain go to these places in the evening or at night.

Yes, absolutely.

These two are both correct:

• Por mucho que me canse el sol
• Por mucho que el sol me canse

They mean the same thing.

The difference is mainly one of:

• emphasis
• rhythm
• style

El sol me canse puts the subject first, which may feel slightly more straightforward to an English speaker.

Me canse el sol sounds very natural in Spanish and is often preferred because Spanish frequently places the subject after the verb, especially when the subject is not the main focus.

Sé que means I know that and introduces the main clause:

• sé que acabaré por volver a este chiringuito

So the structure of the whole sentence is:

• Por mucho que me canse el sol = concessive subordinate clause
• sé que acabaré por volver a este chiringuito = main clause
• porque aquí se cena muy bien = reason

Using sé que makes the statement sound strong and certain. The speaker is not just guessing. They are confident:

• I know I’ll end up coming back

That certainty contrasts nicely with the discomfort caused by the sun.

Volver a means to return to a place.

So:

• volver a este chiringuito = to come back to this beach bar / to return to this chiringuito

Be careful not to confuse this with another very common structure:

• volver a + infinitive = to do something again

For example:

• Volvió a llamar. = He called again.

But here, a este chiringuito is a place, so volver a clearly means return to.

Muy bien means very well, but in this kind of sentence it often has a broader sense than just in a skillful way.

When talking about restaurants or places to eat, comer/cenar bien can mean:

• the food is good
• the meal is satisfying
• the overall dining experience is good

So aquí se cena muy bien is not just saying people are good at eating here. It means:

• the dinners here are very good
• you can eat very well here
• it’s a great place for dinner

It is a very idiomatic way to recommend a place.
