Kwenye menyu ya mkahawa huu, kuna chipsi, kachumbari, na supu ya dengu.

Kwenye is a locative word that can mean on, in, or at, depending on context.

In this sentence, kwenye menyu means on the menu.

So:

• kwenye meza = on the table
• kwenye sanduku = in the box
• kwenye mkahawa = at the restaurant

In Swahili, demonstratives like this usually come after the noun, not before it.

So:

• mkahawa huu = this restaurant
• literally: restaurant this

This is a very common pattern:

• kitabu hiki = this book
• watu hawa = these people

Because Swahili demonstratives have to agree with the noun class of the noun they describe.

Mkahawa belongs to the m-/mi- noun class in the singular, so it takes huu:

• mkahawa huu = this restaurant

By contrast:

• menyu hii = this menu
• mtu huyu = this person

So huu is chosen because it matches mkahawa.

Here, ya links two nouns and often means of.

So:

• menyu ya mkahawa huu = the menu of this restaurant
• more natural English: this restaurant’s menu

This structure is very common in Swahili:

• kitabu cha mwanafunzi = the student’s book
• mlango wa nyumba = the door of the house

It is the same kind of connector.

Supu ya dengu literally means soup of lentils, which English naturally says as lentil soup.

Swahili often expresses this kind of idea with: noun + ya + noun

For example:

• chai ya tangawizi = ginger tea
• juisi ya embe = mango juice
• supu ya dengu = lentil soup

Kuna is an existential expression meaning there is or there are.

In Swahili, the same form kuna is used for both singular and plural in this pattern. English changes between is and are, but Swahili does not here.

So:

• kuna supu = there is soup
• kuna chipsi na supu = there are fries and soup

The number is understood from the noun or from the whole context.

Yes, but the nuance is a little different.

• Kuna chipsi, kachumbari, na supu ya dengu introduces the items that are available.
• Chipsi zipo kwenye menyu focuses specifically on chipsi and says that they are on the menu.

So for listing what a menu contains, kuna is usually the most natural choice.

Swahili does not have articles like English the, a, or an.

Whether something is definite or indefinite is usually understood from context, or shown with other words such as demonstratives.

For example:

• mkahawa huu clearly means this restaurant, so it is definite
• chipsi, kachumbari, and supu ya dengu appear without articles, which is normal in Swahili

Because na means and, and Swahili lists work much like English lists.

So:

• chipsi, kachumbari, na supu ya dengu

is like:

• fries, kachumbari, and lentil soup

The commas separate the earlier items, and na introduces the final one.

Not exactly, and this can confuse English speakers.

In East African Swahili, chipsi usually means French fries.

So:

• for an American English speaker: chipsi = fries
• for a British English speaker: chipsi is close to chips

It usually does not mean what Americans call chips or what Brits call crisps.

Yes. A sentence like this is also possible:

Kuna chipsi, kachumbari, na supu ya dengu kwenye menyu ya mkahawa huu.

That would still be grammatical.

Starting with kwenye menyu ya mkahawa huu puts the location or setting first, a bit like saying: As for this restaurant’s menu...

So the original version sounds natural and helps frame the information before listing the foods.
