簡単な表現ですが、中々言えないものです。 I think this expression is pretty easy, but I can't say it so easily. Is it fine that "All of clerks are chinese in the restaurant" ?
Everyone that works in that restaurant are Chinese.
Hello there.
---
「あのレストランの従業員はみんな中国人です」
"All the workers in that restaurant are Chinese"になります。
"Clerk"はお会計の仕事をする人を指します。
レストランだとレジ担当とかですね。
他にも"Everyone that works in that restaurant are Chinese"
「あのレストランで働いている人は全員中国人だよ」という言い方もあります。

Hope this helps.
The word "employee" refers to someone who works for someone or at a business such as a restaurant or a store. To say that all the employees are Chinese means that everyone who works there are Chinese.
"employee" は雇われて働いている人、例えば会社やレストランの従業員を指します。
"All the employees at the restaurant are Chinese" は「そのレストランで働いている人は皆中国人である」という意味です。
The management at that restaurant hire exclusively Chinese staff.
All of the staff that work there are of Chinese origin.
When we use the word 'exclusively' we mean that the restaurant only hires Chinese staff.
Exclusively can be used in many many contexts for example - "The musicians in that band exclusively use American made instruments." It is also good to mention that the management hire the staff as this adds more detail to the answer.
When we use the word 'origin' in the second answer we mean that all of the staff originate/are born in China.
Both of these answers are formal statements. For an informal answer you could say "all of the staff that work there are Chinese."
exclusively' を使うと、「そのレストランは中国人スタッフしか雇わない」という意味になります。
'exclusively' はさまざまな文脈で使われます。
例えば：
"The musicians in that band exclusively use American made instruments."（そのバンドのミュージシャンはアメリカ製の楽器しか使いません）
また、「経営陣が雇っている」という言い方も、より詳しい説明になるので、いいと思います。
二つ目の例の 'origin' は、スタッフが皆中国生まれであることを表します。
これらの例はどちらもフォーマルな言い方です。
インフォーマルな言い方としては、"All of the staff that work there are Chinese."（そこで働くスタッフは皆中国人です）などがあります。

The kitchen staff, waiters, waitresses and front-of-house staff are all Chinese.
Everyone who works there is Chinese.
All of the above options are correct. Please note that it is not correct to say "staffs": "Staff" is an uncountable noun.
Front-of-house staff refers to the receptionist and hostesses (hostesses show customers to their tables).
