Tôi muốn thử món mì ở quán đó vì bạn tôi nói nó rất ngon.

The sentence follows a very common Vietnamese pattern:

Tôi muốn thử món mì ở quán đó vì bạn tôi nói nó rất ngon.
= I + want + try + the noodle dish + at that restaurant/shop + because + my friend + says/said + it + very delicious

A simple breakdown is:

• Tôi = I
• muốn = want
• thử = try
• món mì = the noodle dish / noodle dish
• ở quán đó = at that shop/restaurant
• vì = because
• bạn tôi = my friend
• nói = say / said
• nó = it
• rất ngon = very delicious / very tasty

So the sentence is basically:

I want to try the noodle dish at that place because my friend says it’s very tasty.

Yes. Vietnamese often puts verbs together without needing a word like to.

• muốn = want
• thử = try

So:

• muốn thử = want to try

This is very normal in Vietnamese. English needs to between the verbs, but Vietnamese does not.

Other similar examples:

• Tôi muốn ăn = I want to eat
• Tôi muốn đi = I want to go
• Tôi muốn xem = I want to watch

thử means to try.

In this sentence, it means the speaker wants to try eating the noodle dish, not necessarily just test it in a general way.

Common uses of thử:

• thử món này = try this dish
• ăn thử = try eating it
• mặc thử = try on clothes
• thử làm = try doing it

So here, muốn thử món mì means want to try the noodle dish.

món is often used for a dish or food item.

• mì = noodles
• món mì = a noodle dish

Using món makes it sound more like a prepared dish you would order or eat at a restaurant.

Compare:

• mì = noodles in general
• món mì = a noodle dish / the noodle dish

In casual speech, Vietnamese speakers might sometimes just say mì, but món mì is perfectly natural when talking about food at a restaurant.

quán usually refers to a shop, eatery, stall, café, or casual restaurant. It often feels less formal than nhà hàng, which is more like restaurant in the full sense.

So:

• quán = small restaurant, café, food shop, stall, casual place
• nhà hàng = restaurant, often more formal

In this sentence, ở quán đó means something like:

• at that place
• at that shop
• at that restaurant

The best English translation depends on context.

In Vietnamese, demonstratives like này, đó, and kia usually come after the noun.

So:

• quán đó = that shop / that restaurant
• món mì đó = that noodle dish
• người đó = that person

This is a very important word order difference from English.

Common pattern:

noun + demonstrative

Examples:

• bàn này = this table
• nhà đó = that house
• xe kia = that car over there

ở often means at, in, or to be located at.

Here, ở quán đó means at that shop/restaurant.

So:

• món mì ở quán đó = the noodle dish at that place

In this sentence, ở quán đó describes where the noodle dish is from.

Examples:

• Tôi ăn ở đây. = I eat here.
• Cô ấy làm việc ở Hà Nội. = She works in Hanoi.
• Món này ở quán kia rất ngon. = This dish at that place is very delicious.

Yes. vì means because.

It introduces the reason for wanting to try the dish:

• Tôi muốn thử món mì ở quán đó = I want to try the noodle dish at that place
• vì bạn tôi nói nó rất ngon = because my friend says it’s very tasty

So the structure is:

main idea + vì + reason

You may also see bởi vì for because, which is slightly longer but similar in meaning.

In Vietnamese, possession is usually expressed as:

noun + possessor

So:

• bạn tôi = my friend
• mẹ tôi = my mother
• nhà tôi = my house
• sách tôi = my book

This is the opposite of English, where the possessor usually comes first:

• my friend
• my mother

So bạn tôi literally looks like friend I, but it means my friend.

Because the first tôi and the second tôi do two different jobs:

• Tôi at the beginning = I
• bạn tôi = my friend

So the sentence contains:

• the speaker: I
• the speaker’s friend: my friend

This repetition is normal in Vietnamese and does not sound strange.

Vietnamese verbs do not change form for tense the way English verbs do.

So nói can mean:

• say
• says
• said

The exact meaning comes from context.

In this sentence, English could translate it as either:

• because my friend says it’s very delicious
• because my friend said it was very delicious

If you want to make the past clearer in Vietnamese, you could add a time marker or aspect word, such as:

• đã nói = said
• hôm qua bạn tôi nói... = yesterday my friend said...

But without extra markers, nói is neutral.

nó here refers to món mì — the noodle dish.

So:

• bạn tôi nói nó rất ngon = my friend said it is very tasty

Using nó to refer to a thing is normal.

Here it works like English it.

That is a very good question.

Yes, nó can sound rude or impolite when used for a person, depending on the situation. But for things, animals, or sometimes children in certain contexts, it can be normal.

In this sentence, nó refers to the dish, not a person, so it is completely fine.

So:

• referring to a dish with nó = normal
• referring to a person with nó = can sound rude unless the relationship/context makes it acceptable

Sometimes, yes.

Vietnamese often omits words when the meaning is clear from context. So you might hear:

• Tôi muốn thử món mì ở quán đó vì bạn tôi nói rất ngon.

This can still be understood as:

• I want to try the noodle dish at that place because my friend said it’s very tasty.

However, including nó makes the reference clearer:

• nó rất ngon = it is very delicious

So the original sentence is clear and natural.

Both are possible.

• rất ngon = very delicious
• rất là ngon = very, very delicious / really delicious

rất ngon is more neutral and straightforward.
rất là ngon adds a bit more emphasis or conversational feeling.

So the sentence with rất ngon is perfectly natural and standard.

Mostly, ngon is used for food and drink, meaning:

• delicious
• tasty

Examples:

• Cơm ngon. = The rice is delicious.
• Cà phê này ngon. = This coffee is tasty.

Sometimes it can be used more broadly in informal speech, but for learners, the safest meaning is delicious/tasty, especially with food.

Yes. The original sentence is already natural, but Vietnamese has many small variations.

For example:

• Tôi muốn thử mì ở quán đó vì bạn tôi nói rất ngon.
• Tôi muốn ăn thử món mì ở quán đó vì bạn tôi bảo nó ngon lắm.

A few notes:

• ăn thử emphasizes actually trying it by eating it
• bảo can replace nói in casual speech
• ngon lắm means very delicious with a more spoken feel

But the original sentence is clear, correct, and natural for learners to use.

It is understood as the noodle dish from/at that place, not trying the dish while physically at that place.

So:

• món mì ở quán đó = the noodle dish at that restaurant/shop

The phrase ở quán đó is describing món mì, not the action thử.

If you wanted to emphasize doing the trying there, you might phrase it differently depending on context. But in this sentence, the natural reading is that the dish belongs to or is served at that place.
