Because they do two different jobs:

• 가는 in 자주 가는 카페 means the cafe that [people] often go to.
  Here, 가는 is the noun-modifying form of 가다, so it describes 카페.
• 가 봤어 is the main verb of the sentence and means went / tried going.

So the sentence structure is roughly:

• 동네 주민들이 자주 가는 카페를 = the cafe that neighborhood residents often go to
• 오늘 처음 가 봤어 = I went there for the first time today / I tried going there today for the first time

Korean often uses the same verb twice like this when one instance modifies a noun and the other is the main action.

It means the cafe that local residents often go to.

Breakdown:

• 동네 = neighborhood
• 주민들 = residents
• 이 = subject marker, attached here as 주민들이
• 자주 = often
• 가는 = going / that go to
• 카페 = cafe

So literally it is something like:

the cafe that neighborhood residents often go to

This is a very common Korean pattern:

• [subject] + [verb in noun-modifying form] + noun

For example:

• 제가 좋아하는 음식 = the food that I like
• 친구가 사는 집 = the house where my friend lives
• 학생들이 자주 쓰는 표현 = the expression students often use

이/가 marks 주민들 as the subject of the descriptive clause 자주 가는.

In 동네 주민들이 자주 가는 카페, the people doing the action go often are the residents, so 주민들이 is the subject of that clause.

If you changed it to 주민들은, the nuance would shift toward topic or contrast, something like:

• as for the residents, they often go to...

But in this sentence, 이/가 is the natural neutral choice because the clause is simply identifying which cafe it is:

• the cafe that residents often go to

So 이/가 is very common inside relative clauses like this.

Good question. In Korean, some place nouns can take 을/를 with movement verbs like 가다, especially when the place is being treated as the destination in a more object-like way.

So:

• 카페를 갔어
• 카페에 갔어

Both may appear, but they are not always identical in feel.

In this sentence, 카페를 오늘 처음 가 봤어 sounds natural because the speaker is talking about trying that cafe as a destination/experience. The cafe is almost being treated like a place one checks out or visits.

That fits well with 가 보다, which often has the nuance of trying something out.

So 카페를 가 봤어 feels like:

• I tried going to that cafe
• I checked that cafe out

오늘 처음 means for the first time today or today, for the first time.

Breakdown:

• 오늘 = today
• 처음 = first time

So 오늘 처음 가 봤어 means:

• I went there for the first time today
• Today was my first time going there

Important nuance: It does not mean today was the first day it opened or anything like that. It means today was my first visit.

Not exactly. 가 봤어 is 가다 + 보다, where 보다 adds the meaning of trying something or doing it to see what it’s like.

So:

• 갔어 = I went
• 가 봤어 = I tried going / I went and experienced it

In this sentence, 가 봤어 suggests:

• the speaker had heard about the cafe
• and finally tried going there

So the nuance is more natural in English as:

• I finally went to that cafe today for the first time
• I tried going to that cafe today for the first time

This V-아/어 보다 pattern is extremely common:

• 먹어 봤어 = I tried eating it / I’ve tried it
• 읽어 봤어 = I tried reading it
• 해 봤어 = I tried doing it

Because 아/어 보다 is a fixed grammar pattern.

With 가다, the stem is 가-, and it combines with 아 보다:

• 가 + 아 보다 → 가 보다

Then in past tense:

• 가 봤어

This comes from:

• 가 보았어 → contracted to 가 봤어

So the pattern is:

• 먹다 → 먹어 보다 → 먹어 봤어
• 하다 → 해 보다 → 해 봤어
• 가다 → 가 보다 → 가 봤어

Because Korean often omits subjects when they are obvious from context.

In 동네 주민들이 자주 가는 카페를 오늘 처음 가 봤어, the only explicitly marked subject is 동네 주민들이, but that belongs to the relative clause:

• the residents often go to

The subject of the main verb 가 봤어 is omitted, but it is understood as I in most contexts.

So the full meaning is:

• I went to the cafe that neighborhood residents often go to for the first time today

Omitting 내가 is very natural in Korean and usually sounds smoother unless there is a reason to emphasize I.

Yes, it uses the present noun-modifying form, but in Korean that form often covers habitual or general actions as well.

So 자주 가는 카페 means:

• a cafe they often go to
• their usual cafe
• a cafe they frequent

It does not mean they are literally going there right now. In this kind of structure, the present modifier often expresses:

• general facts
• repeated actions
• habits
• characteristics

For example:

• 제가 읽는 책 = the book I am reading / the book I read
• 학생들이 많이 찾는 식당 = the restaurant students often look for / visit a lot

So 가는 here is very naturally understood as habitual because of 자주.

Yes, that is a good translation, but it may sound a little stiff in English.

More natural translations would be:

• I went to that cafe local residents often go to for the first time today.
• Today, I went for the first time to the cafe that local residents often go to.
• I finally tried the cafe that local residents often go to, for the first time today.

One subtle point: because 카페를 does not have something like 그 before it, the sentence does not force that cafe in a strict grammatical sense. But in context, English often uses that naturally because the cafe is being identified by the clause local residents often go to.

가 봤어 is casual/informal speech, often called 반말.

The polite version would be:

• 동네 주민들이 자주 가는 카페를 오늘 처음 가 봤어요.

That is the same meaning, just polite.

You could also say:

• 동네 주민들이 자주 가는 카페에 오늘 처음 가 봤어요.

Both are possible, with slightly different nuance depending on whether you feel the cafe more as a destination or as a place you tried out.

Yes.

• 처음 갔어 = I went for the first time
• 처음 가 봤어 = I tried going for the first time / I went and experienced it for the first time

가 봤어 often feels a bit more experiential. It can imply:

• curiosity
• trying something out
• checking a place out
• seeing what it was like

So in this sentence, 처음 가 봤어 sounds especially natural because the speaker is talking about a cafe known to be popular with local residents and finally trying it.

Sometimes yes, depending on context, but not literally by itself.

동네 just means neighborhood or local area. It does not itself contain my. But in everyday speech, if someone says 동네 주민들, listeners often understand it as:

• the residents in my neighborhood
• the local residents around here

So possible translations include:

• local residents
• people in the neighborhood
• residents in my neighborhood if the broader context supports that

In English, local residents is often the smoothest choice.
