sono mise no sooseezi ha sukosi takai desu ga, totemo oisii desu.

その means that, but specifically that ... near you / the one we already mentioned.

Japanese has a three-way distinction:

• この = this ... near me
• その = that ... near you / that one we’re talking about
• あの = that ... over there / away from both of us

So その店 means that shop/store.

の links nouns together.

Here, その店のソーセージ literally means something like:

• that shop’s sausage(s)

In natural English, this often becomes:

• the sausages at that shop
• the shop’s sausages

So の is not only for ownership like John’s book. It can also show connection, association, or origin.

ソーセージ is a loanword, borrowed from a foreign language, so it is written in katakana.

Katakana is commonly used for:

• foreign loanwords
• some brand names
• sound effects
• emphasis in some cases

So ソーセージ is just the normal Japanese way to write sausage.

Japanese nouns usually do not change form for singular vs. plural.

So ソーセージ can mean:

• sausage
• sausages

You understand the number from context.

In this sentence, English might translate it as sausages because that sounds more natural, but the Japanese word itself does not mark plural.

は marks the topic of the sentence.

Here, the topic is:

• その店のソーセージは = as for the sausages at that shop...

Then the sentence says something about that topic:

• they are a little expensive
• but very delicious

So は is not exactly the same as the English subject marker. It introduces what the sentence is about.

少し means a little or slightly, and it modifies the adjective 高い.

So:

• 少し高い = a little expensive

This is similar to English word order in a little expensive.

A very common alternative in conversation is ちょっと, which often sounds a bit softer and more natural in casual speech:

• ちょっと高い

It can mean either, depending on context.

Common meanings of 高い include:

• high
• tall
• expensive

In this sentence, because it is describing ソーセージ, it means:

• expensive

So 少し高い means a little expensive, not a little high.

高い and おいしい are い-adjectives.

In polite speech, you can add です after an い-adjective:

• 高いです
• おいしいです

This makes the sentence polite.

Important point:

• the adjective itself already carries the meaning
• です adds politeness
• it is not the same as saying 高いだ, which is incorrect

Compare:

• 高い。 = plain/casual
• 高いです。 = polite

Here, が means but.

So the structure is:

• 少し高いですが、とてもおいしいです。
• They’re a little expensive, but very delicious.

This が connects two ideas with contrast:

• negative or less favorable point: a little expensive
• positive point: very delicious

It often sounds a bit smoother and softer than a very direct English but.

The comma helps separate the two parts of the sentence:

• その店のソーセージは少し高いですが
• とてもおいしいです

It makes the sentence easier to read.

In Japanese, commas are often used more flexibly than in English, so punctuation can vary. You may sometimes see similar sentences with or without a comma.

とても means very.

So:

• とてもおいしい = very delicious / very tasty

It strengthens the adjective.

A few common intensifiers like this are:

• とても = very
• すごく = very, really
• かなり = quite, fairly

Yes, it is natural and polite.

It sounds like a standard spoken or written comment, such as in a review or recommendation.

A more casual version might be:

• その店のソーセージは少し高いけど、とてもおいしい。

Here:

• けど is a casual version of ですが
• final です is removed for a casual tone

So the original sentence is a good polite model for learners.

Because 店 is a broad word.

Depending on context, it can mean:

• shop
• store
• sometimes restaurant or business

So その店のソーセージ could refer to sausages sold by that shop, or sausages served there, depending on the situation.

Japanese often leaves this kind of detail to context.
