Sentences correction

Use these:

When was this restaurant established?
When did this restaurant open?
How long has this restaurant been here?

Thank you very much. Is it wrong to say: what year was this restaurant established/opened?

In what year was this restaurant established?
It's OK, but usually "established" is used for manufacturing, publishing, banking, grocery chains, fast food chains or other similar large businesses. It is not typically used for one restaurant in one location.

You can also say:
In what year did this restaurant open?

AnonymousIs it wrong to say: what year was this restaurant established/opened?

No, but it is unusually limiting. The answer may be 'April'. In my neck of the woods, restaurants often do not last a year.

Why would the answer be April if I asked about the year. Does the question just sound wrong? Yes, true some restaurants don't last very long.

Did I say that last sentence correctly: don't last very long? Could I say: don't last for years?

Thank you for your help

AnonymousDoes the question just sound wrong?

Yes. 'When' seems the open unmarked choice to me. We ask the year for wine vintages.

So I understand that the questions starting with when that you had suggeated earlier would be your choice. Right?

lastly, would you please tell me if what I wrote is correct:
Restaurants don't last very long.
Restaurants dont last for many years.

Thank you so much

AnonymousRestaurants don't last very long.Restaurants dont last for many years.

OK, but again I prefer the first as a general statement.

Sorry to bother you but would the second sentence be correct if I excluded the 'for', restaurants don't last many years. And which would you prefer if it would be correct?

There is just many ways to write in english, so I have doubts sometimes.

Many thanks again!
