Bu mahalledeki pastane, bana göre en lezzetli tatlıları satıyor.

Mahalledeki means the one in the neighborhood or located in the neighborhood.

It is built like this:

• mahalle = neighborhood
• -de = in / at
• -ki = a suffix that turns a location phrase into something adjective-like

So:

• mahallede = in the neighborhood
• mahalledeki pastane = the bakery in the neighborhood / the bakery that is in the neighborhood

With bu, it becomes:

• bu mahalledeki pastane = the bakery in this neighborhood

Because in Turkish, modifiers usually come before the noun they describe.

So instead of saying:

• the bakery in this neighborhood

Turkish literally structures it more like:

• this neighborhood-in-the bakery

That sounds strange in English, but it is completely normal in Turkish.

A very common pattern is:

• [describing phrase] + noun

For example:

• masadaki kitap = the book on the table
• okuldaki öğrenciler = the students at school
• bu mahalledeki pastane = the bakery in this neighborhood

Bana göre means according to me, in my opinion, or more naturally in English, to me / in my view.

It is made of:

• ben = I
• bana = to me
• göre = according to / in relation to

So:

• bana göre = according to me

In this sentence, it gives a personal opinion:

• bana göre en lezzetli tatlıları satıyor
• in my opinion, it sells the most delicious desserts

Because göre requires the dative case.

So Turkish says:

• bana göre = according to me
• sana göre = according to you
• ona göre = according to him/her/it

You cannot say ben göre.

This is just something to learn as a fixed pattern:

• X-e / X-a göre = according to X

En lezzetli means the most delicious.

It is formed like this:

• lezzet = flavor, taste
• lezzetli = tasty / delicious
• en lezzetli = most delicious

In Turkish, the superlative is usually made with en + adjective:

• en büyük = biggest
• en güzel = most beautiful
• en pahalı = most expensive
• en lezzetli = most delicious

So Turkish does not change the adjective itself the way English sometimes does with -est. It usually just adds en before the adjective.

The suffix -li / -lı / -lu / -lü often means with, having, or characterized by.

So:

• lezzet = flavor/taste
• lezzetli = with flavor, flavorful, delicious

This suffix is very common:

• tuzlu = salty
• şekerli = sugary
• sesli = with sound / voiced
• evli = married (literally something like with a home/spouse, historically)

In everyday use, you should usually just learn the full adjective:

• lezzetli = delicious

Here, tatlıları is the definite direct object: the desserts.

Breakdown:

• tatlı = dessert / sweet
• tatlılar = desserts
• tatlıları = the desserts

In Turkish, a specific/definite direct object usually takes the accusative ending.

So:

• tatlı satıyor = it sells dessert / desserts
• tatlıları satıyor = it sells the desserts

In this sentence, en lezzetli tatlıları means the most delicious desserts, so the definite object form is natural.

Also note: tatlıları can sometimes be ambiguous in isolation, because it can also mean his/her/their desserts in other contexts. Here, the meaning is clearly the desserts because of the sentence context.

Satıyor is the present continuous form, but in Turkish it is often also used for what English expresses as a general present.

• satmak = to sell
• satıyor = is selling / sells

So in Turkish, satıyor can mean either:

• is selling right now, or
• sells in general

In this sentence, it most naturally means:

• sells

You could also hear satar in some contexts for habitual or general meaning, but satıyor is extremely common for everyday present-time statements.

The sentence is:

• Bu mahalledeki pastane, bana göre en lezzetli tatlıları satıyor.

A rough breakdown is:

• Bu mahalledeki pastane = the bakery in this neighborhood
• bana göre = in my opinion
• en lezzetli tatlıları = the most delicious desserts
• satıyor = sells

Turkish basic word order is often Subject + Object + Verb, with the verb at the end.

So the core structure is:

• [subject] [object] [verb]

Here, bana göre is an inserted opinion phrase, so the sentence feels like:

• [subject], [in my opinion], [object] [verb]

Yes. Turkish word order is fairly flexible, especially for adverbial phrases like bana göre.

These are all possible, with slightly different emphasis:

• Bana göre bu mahalledeki pastane en lezzetli tatlıları satıyor.
• Bu mahalledeki pastane bana göre en lezzetli tatlıları satıyor.
• Bu mahalledeki pastane en lezzetli tatlıları bana göre satıyor. ← much less natural here

The most natural places are usually near the beginning or after the subject.

So the original sentence is very natural, but not the only possible order.

No, it is not strictly necessary.

• Bu mahalledeki pastane bana göre en lezzetli tatlıları satıyor.

is also perfectly fine.

The comma just helps mark a pause before bana göre, almost like:

• The bakery in this neighborhood, in my opinion, sells the most delicious desserts.

So it is more about style and readability than grammar.

Turkish has no articles like a or the.

Instead, definiteness is often understood from context, word order, and case marking.

In this sentence:

• bu mahalledeki pastane is understood as a specific bakery: the bakery in this neighborhood
• tatlıları has accusative marking, which helps show a specific/definite object: the desserts

So Turkish does not need a separate word for the.

This is very common:

• Kitap masada. = The book is on the table. / A book is on the table.
• Context tells you which one is meant.

It can mean both, depending on context.

• tatlı as an adjective = sweet
• tatlı as a noun = dessert / sweet food

In this sentence, tatlıları is clearly the noun, so it means:

• desserts
• or more loosely, sweets

Because the sentence talks about a pastane (bakery/patisserie), desserts is the most natural translation here.

Pastane usually means a pastry shop, patisserie, or sometimes a bakery that specializes in cakes, pastries, and desserts.

So it is not always exactly the same as an English-style bread bakery.

In this sentence, pastane fits very well with tatlılar because a pastane is exactly the kind of place that sells desserts and pastries.
