で marks the place where an action happens. Here, the action is comparing.

• レストランで = at/in the restaurant
• に is more often used for destination, existence, or a specific point in time

So レストランで味を比べる means compare tastes at the restaurant, not go to the restaurant.

を marks the direct object of the verb. The thing being compared is 味.

• 味を比べる = compare tastes/flavors

The verb 比べる is a transitive verb, so it normally takes を for the thing being compared.

It is made from:

• 比べる = to compare
• 比べて = the て-form
• みる after a て-form = to try doing something
• ましょう = polite let's ...

So:

• 比べてみましょう = let's try comparing
• not just let's compare, but with a nuance of trying it and seeing

〜てみる adds the idea of trying something out.

Compare:

• 比べましょう = let's compare
• 比べてみましょう = let's try comparing

The second one sounds a little softer and more exploratory, like let's give it a try.

Good question. In Japanese, the second item is often omitted if it is obvious from context.

A fuller pattern would be something like:

• AとBを比べる = compare A and B
• Aの味をBの味と比べる = compare A's taste with B's taste

In this sentence, only 味を比べて appears, so the listener is expected to understand which tastes are being compared from the situation.

Because 新しい is an い-adjective.

い-adjectives directly modify nouns:

• 新しいレストラン = a new restaurant

By contrast:

• きれいなレストラン uses な because きれい is a な-adjective
• 日本のレストラン uses の because 日本 is a noun

So 新しいレストラン is the normal form.

It can mean either, depending on context.

• taste = the taste of food
• flavor = often a more natural English translation in food contexts

So 味を比べる could be understood as:

• compare the tastes
• compare the flavors

English may choose whichever sounds more natural in the situation.

Japanese nouns usually do not show singular vs. plural the way English does.

So 味 could mean:

• taste
• tastes
• flavor
• flavors

You figure that out from context. In this sentence, English will often use tastes or flavors, but Japanese itself does not have to mark that.

Japanese often leaves out the subject when it is clear from context.

Because the sentence ends in ましょう, the implied subject is usually we:

• 比べてみましょう = let's try comparing

So a separate 私たちは is unnecessary unless the speaker wants extra emphasis.

The dictionary form is 比べる.

This is an ichidan verb, so the て-form is made like this:

• 比べる → 比べて

Then:

• 比べてみる
• 比べてみましょう

So the sentence uses the verb in a connected form, not the plain dictionary form.

They are read:

• 味 = あじ
• 比べてみましょう = くらべてみましょう

The whole sentence is:

• あたらしい レストラン で あじ を くらべて みましょう。

No. Normal Japanese is usually written without spaces:

• 新しいレストランで味を比べてみましょう。

Spaces are often added in beginner materials to make the structure easier to see. They are a teaching aid, not standard everyday writing.
