Traducción - Francés-Inglés - Le quartier de Montmartre

There's an error of translation in the following part :

"We found, by chance, the brasserie where the film Amélie was shot, which was worth a visit; the food was great and the staff were pleasant."

The original says :

Nous avons trouvé par hasard la "brasserie" où a été tourné le film "Amélie Poulain", cela vaut le détour car on y mange bien et le personnel est sympatique. ("We found, by chance, the brasserie where the film Amélie was shot, it was worth a visit because the food was great and the staff were pleasant." )

In this same second sentence, I would write:

"the food is great, and the staff is pleasant."
["...on y mange bien et le personnel est..."] Surely, one can still eat well there, and the staff continues to be pleasant...
Just my opinion.

Moreover:

"on y mange bien" means that the food is good...
"Great" is quite another level of quality, isn't it?

Francky; I would have said the "because" was implied in this case, but yes for word-for-word accuracy it could be added.

Lev, agreed on your points, except you can't say "the staff is" in English because this word is plural. We could put "the staff are" in this case.

Maybe you are right, arbctb...
Excuse me the doubt, but that's a difficult word if you think of a body or group of people, which would be singular...

Definitely, it's one of those exceptions. Like the word "sheep"...

Thank you for your feedback though; it is useful.

OK. I take your point if you know better
Thanks !
