Hi,girigiri.
If I write “work”, reader would not see the staff have pride in MAUZEN because MARUZEN is a prestigious, time-honored company.
Every waitress can have pride in their work, but it’s not what I wanted to say. What should I have written?

M&C Café is run by MARUZEN book chain store. They say their first president named Hayashi is the first person who made Hayashi Rice.
M&C Cafe, run by MARUZEN book store chain, claim that their first president, Hayashi, was the first (person) to make Hayashi Rice. - Only "is←was" as a mandatory correction.

.
I thought “He was the first person” sounds like he is not the first person anymore, but I try to see how English goes. It’s too difficult!

Getting nit-picky:
I ate Hayashi Rice at M&C Café today.
Hayashi Rice is similar to beef stew, and an ordinary dish in Japan.
At an M&C Cafe today, I had Hayashi Rice. It is an ordinary dish in Japan, similar to beef stew.

You put M&C café first. Does it mean the Café is more important than Hayashi Rice?
What does the order mean?

It’s very nice place to have a break after shopping.
"a very nice place" (probably a matter of local dialect) have←take;

You mean “have” is correct? I wrote “have a break”.

「現在完了時制 」について
The teaching that "has been ~" is a present perfect form first came to my attention a couple of years ago. 当惑しました。 On checking ESL and TEFL sites, I discovered that those sites teach "has been ~" as the present perfect form. 徹底的にびっくりした。

“has been” is a present perfect form, but they say it’s the present perfect form. OK. (Am I following you?)

In response, I sent emails to some of the sites, asking for clarification of two issues. To repeat the phrasing of the key points of those emails:
1/ I have not been able to find reference to the "is + past participle" present perfect form - could you direct me to the area which explains it please.

You have not been able to find examples with the “is + past participle” present perfect form. And you asked them to tell you where the examples or explanations are.
I don’t know the difference between “the ‘is + participle present perfect form’” and “a”.
Is a “is + past participle present perfect form” “She has been locked away in a tower for 10 years”, for example?

2/ The "has been ~" form seems to have only its present perfect usage explained. Does your site explain its more common use as a progressive form?
To date: None of the sites that I e-mailed has given any response.

A progressive form? Is it “She has been waiting for a knight to rescue her”, for example?
I’m sorry. I don’t see what you mean.
