Da li Vi želite da idete u restoran danas?

Da li is a very common way to form a yes/no question in Serbian.

So:

• Vi želite da idete u restoran danas. = You want to go to the restaurant today.
• Da li Vi želite da idete u restoran danas? = Do you want to go to the restaurant today?

It works a bit like adding do/does in English to make a question.

There are other ways to ask yes/no questions in Serbian, but da li is one of the most standard and beginner-friendly patterns.

Vi means you in the formal or plural sense.

In this sentence, it is capitalized because it is being used as a polite singular you, similar to formal you when speaking respectfully to one person.

So:

• ti = informal singular you
• vi / Vi = plural you, or formal singular you

Capitalizing Vi is common in polite writing, though in everyday writing you may also see lowercase vi. The capitalization adds respect.

The difference is formality.

• Da li Vi želite da idete u restoran danas? = formal/polite
• Da li ti želiš da ideš u restoran danas? = informal, used with a friend, child, family member, etc.

Notice that changing from Vi to ti also changes the verb forms:

• Vi želite
• ti želiš

Serbian verbs must agree with the subject.

Želite is the 2nd person plural form of the verb želeti = to want.

Because Vi is either:

• plural you, or
• formal singular you

the verb takes the 2nd person plural form.

Present tense of želeti:

• ja želim = I want
• ti želiš = you want
• on/ona/ono želi = he/she/it wants
• mi želimo = we want
• vi želite = you want
• oni/one/ona žele = they want

So Vi želite literally means you want.

This is a very important Serbian pattern.

After many verbs, especially want, Serbian often uses:

• da + present tense verb

So instead of saying a structure exactly like English to go, Serbian says:

• želite da idete = you want to go

Here:

• da introduces the following action
• idete is the present tense form of ići = to go

This da + present tense structure is extremely common in Serbian.

Idete is the 2nd person plural present tense form of ići = to go.

It matches Vi, just like želite does.

So:

• Vi želite = you want
• da idete = that you go / to go

Together:

• Vi želite da idete = you want to go

Because Serbian uses agreement very consistently, both verbs reflect the subject Vi.

Because the sentence expresses:

1. a main action/state: want
2. a second action: go

In English:

• Do you want to go...?

In Serbian:

• Da li Vi želite da idete...?

So:

• želite = main verb, want
• idete = dependent verb, go

This is normal and very common.

Because u can mean either:

• in
• into / to

and the case depends on the meaning.

Here, the idea is motion toward a destination: go to a restaurant.
So Serbian uses u + accusative:

• u restoran = to the restaurant

If you were talking about being inside the restaurant, you would use u + locative:

• u restoranu = in the restaurant

So compare:

• Idem u restoran. = I am going to the restaurant.
• Ja sam u restoranu. = I am in the restaurant.

It can mean either, depending on context.

Serbian has no articles like English a/an/the. So restoran by itself can mean:

• a restaurant
• the restaurant

The listener figures it out from context.

So u restoran could be understood as:

• to a restaurant
• to the restaurant

In many learning materials, it is often translated simply as to the restaurant, but the Serbian form itself does not mark that distinction.

Yes, danas = today can move around more freely than in English, although some positions sound more natural than others.

Your sentence:

• Da li Vi želite da idete u restoran danas?

Also possible:

• Da li Vi danas želite da idete u restoran?
• Da li danas želite da idete u restoran?

The exact placement can slightly change emphasis:

• ...u restoran danas emphasizes today at the end
• danas želite... brings today earlier into focus

Serbian word order is fairly flexible, but not random.

It can often be omitted.

Serbian frequently drops subject pronouns because the verb ending already shows who the subject is.

So you could say:

• Da li želite da idete u restoran danas?

This still clearly means Do you want to go to the restaurant today? in a formal or plural sense, because želite tells us the subject is vi/Vi.

Including Vi can add:

• politeness
• emphasis
• clarity

Yes. A very natural version is:

• Da li želite da idete u restoran danas?

This is shorter because the subject pronoun is omitted.

You may also hear other question patterns, such as:

• Želite li da idete u restoran danas?

This is another standard way to ask the same yes/no question. It is slightly more compact and very common in speech and writing.

So all of these are good:

• Da li Vi želite da idete u restoran danas?
• Da li želite da idete u restoran danas?
• Želite li da idete u restoran danas?

It is formal/polite, mainly because of Vi.

The sentence sounds appropriate when speaking to:

• a stranger
• an older person
• a customer
• someone in a professional setting
• one person you want to address respectfully

If you were talking to a friend, you would normally use ti instead:

• Da li želiš da ideš u restoran danas?

So the original sentence is polite and perfectly natural in a formal context.
