آشپزخانه آن رستوران هم تمیز است.

A careful pronunciation is āšpazxâne-ye ân resturân ham tamiz ast.

A more everyday spoken version is often closer to:

āšpazxune-ye un resturân ham tamize

So learners may hear a more formal and a more conversational version of the same sentence.

Because Persian usually does not use a separate word like English of in this kind of phrase. Instead, it uses the ezafe construction, a linking sound between nouns.

So this part is understood as:

آشپزخانهِ / آشپزخانه‌ی / آشپزخانهٔ آن رستوران
= the kitchen of that restaurant

In pronunciation, the link is -ye here:

āšpazxâne-ye ân resturân

This is very common in Persian writing. After a word ending in ـه, the ezafe is often pronounced but not always fully marked in ordinary spelling.

So you may see:

آشپزخانه آن رستوران

but it is read as:

آشپزخانه‌ی آن رستوران or آشپزخانهٔ آن رستوران

A learner should get used to the fact that Persian often leaves the ezafe unwritten even when it is definitely there in speech.

Because Persian demonstratives like این and آن normally come before the noun:

• این رستوران = this restaurant
• آن رستوران = that restaurant

So آن رستوران follows the normal Persian pattern.

هم usually means also, too, or as well.

In this sentence, it means that the subject phrase is being added to something already mentioned. So the idea is:

• The kitchen of that restaurant is also clean
• That restaurant's kitchen is clean too

A useful rule is that هم often comes after the word or phrase it relates to.

Because in Persian, predicate adjectives usually come before the verb to be.

So the structure is:

subject + adjective + copula

Here that gives:

• آشپزخانه آن رستوران هم = the kitchen of that restaurant too
• تمیز = clean
• است = is

So the literal order is something like:

The kitchen of that restaurant too clean is

That is normal Persian word order.

است is the formal written form of is.

So:

• تمیز است = is clean

In everyday speech, speakers often use the shorter spoken form:

• تمیزه

So the sentence in casual spoken Persian would very often end with تمیزه instead of تمیز است.

Not directly. Persian does not have a definite article like English the.

Definiteness is usually understood from context or shown in other ways, such as with این or آن.

Here, آن رستوران already means that restaurant, so the phrase is naturally definite.

No. Persian adjectives do not change the way English learners might expect from some other languages.

So تمیز stays تمیز whether the noun is:

• singular or plural
• masculine or feminine

In fact, Persian does not have grammatical gender like many European languages do.

Yes. A very common spoken version would be:

آشپزخونه‌ی اون رستوران هم تمیزه

This is more conversational because:

• آشپزخونه is the spoken form of آشپزخانه
• اون is the spoken form of آن
• تمیزه is the spoken form of تمیز است

So if you hear this version in real life, it is the same basic sentence in a more natural spoken register.
