Restauranten var for støjende, så vi gik videre til en anden.

In Danish, the definite article is usually attached to the end of the noun instead of being a separate word.

• restaurant = a restaurant
• restauranten = the restaurant

So Restauranten var for støjende means The restaurant was too noisy.

This is very common in Danish:

• bog → bogen = the book
• bil → bilen = the car

In Danish, for can mean too when it comes before an adjective or adverb.

So:

• for støjende = too noisy
• for dyr = too expensive
• for sent = too late

This is different from English, where for usually has other meanings. A learner often expects too, but Danish uses for in this structure.

Støjende means noisy.

It comes from the noun støj, which means noise. The ending -ende can form an adjective with the sense of causing or characterized by something.

So:

• støj = noise
• støjende = noisy / making noise

In everyday Danish, støjende is a normal adjective. In this sentence, it describes the restaurant.

Var is the past tense of være, which means to be.

So:

• er = is / are
• var = was / were

In the sentence:

• Restauranten var for støjende = The restaurant was too noisy

Since the whole sentence talks about a past situation, Danish uses the past tense var.

Here så means so in the sense of therefore / as a result.

The sentence has two linked ideas:

• the restaurant was too noisy
• as a result, we went on to another one

So:

• ..., så vi gik videre ... = ..., so we moved on ...

This is a very common way to connect cause and result in Danish.

Because så is functioning here as a coordinating conjunction, similar to English so.

After a coordinating conjunction like this, Danish keeps normal main-clause word order:

• så vi gik videre
• subject vi comes before the verb gik

If så were being used differently, for example as an adverb at the start of a clause, you could get inversion:

• Så gik vi videre = Then we moved on

So in this sentence:

• ..., så vi gik videre ... = ..., so we moved on ...

No inversion is needed.

Gik is the past tense of gå, which usually means to walk or to go.

Here it means went:

• gå = to go / to walk
• gik = went

So:

• vi gik videre = we went on / we moved on

Danish often uses gå in places where English uses go.

Videre means further / on.

In this sentence, gik videre means something like:

• went on
• moved on
• continued to another place

So the idea is that they did not stay at that restaurant; they went somewhere else.

You can also see videre in other expressions:

• arbejde videre = continue working
• læse videre = continue reading / continue studying
• gå videre = move on

Because Danish, like English, often leaves out a noun when it is obvious from context.

So til en anden literally means to another one. The noun restaurant is understood.

Full version:

• til en anden restaurant = to another restaurant

Shorter natural version:

• til en anden = to another one

This omission is very common and sounds natural.

Because restaurant is a common gender noun in Danish:

• en restaurant

When anden refers back to a common-gender noun, it stays in the common-gender form:

• en anden = another one / another restaurant

If the noun were neuter, you would use et andet:

• et hus = a house
• et andet hus = another house

So here:

• restaurant → common gender
• therefore en anden

Yes. ... til en anden restaurant is completely correct.

But ... til en anden is more natural here because the noun has just been mentioned already. Danish often avoids repeating a noun when it is obvious.

So both are correct:

• så vi gik videre til en anden
• så vi gik videre til en anden restaurant

The first one sounds smoother in this context.

This is an important difference:

• meget støjende = very noisy
• for støjende = too noisy

Meget just describes a high degree. For means the degree is excessive or a problem.

So in this sentence, for støjende suggests the noise was bad enough that it caused them to leave.

The tricky part is støj.

A rough guide:

• støjende sounds approximately like STOY-en-duh

But that is only approximate. Important points:

• ø is a vowel English does not really have
• j in støj helps create a sound a bit like the y in toy, but not exactly
• the final -e in Danish is often a light uh sound

If you want to focus on one part, practice støj first, since that is the hardest bit for many English speakers.
