Is it so bad to say "A cafe is at the corner"?

Question

My grammar book says it's "There is a cafe at the corner" but can't say "A cafe is at the corner". Is it really so? I feel that the rule is prohibiting free ways of expressing things.

[Edit] It seems like my careless switching words made confusions and problems. I'd like to go back to the original sentences: "There is a restaurant around the corner." vs. "A restaurant is around the corner."

Maybe 'can't say' was too much and I should have said 'don't say', my grammar book is written in my native language.

So, now I understand that people usually say "There is a restaurant around the corner" in a day-to-day conversation, This is the common way of saying, but in a novel you might also find "A restaurant is around the corner", or you can use it when you are giving a direction.

So both are grammatically correct, but the nuance is slightly different and not really convertible each other. I hope I got this correct.

Answer 1

EDIT to Add:
A cafe is at the corner is a perfectly fine English sentence. Even The cafe is on the corner is fine--even if you have never heard of this cafe before. Someone can tell you The cafe is on the corner.

Origial answer:
This is an arbitrary rule that is limiting your ways of expressing things. Both sentences are fine. The use of "there is' is the so-called existential construction. It puts a "dummy they" in as the subject and moves the real (or "logical") subject of the verb to the predicate side of the verb to be.

As the wikipedia description says, this construction is used to refer to the presence or existence of something, from There is a God to There is a turd in your commode.

So, "There is a cafe at the corner" declares the existence of a cafe at the corner. However, in a description of a town, A cafe is at the corner works as well. Either one works fine when giving directions, although the existential construction may be more common.

One can also say Here is a cafe at the corner and, again, There is a cafe at the corner, showing that these uses of there and here are deitic, which just describes something from the place in space of the speaker. "There" would mean "over there at that corner" while "here" would mean "right here at this corner." Note the change from the determiner the to the deitic or demonstrative pronouns that and this, which both also reference the cafe from the place in space of the speaker.

Answer 2

A cafe is on the corner.

In English we like to put new information at the end of the sentence where it has emphasis. We like to put old information at the beginning of the sentence. Because we have already talked about these things they are easier to process. If we don't have any old information in a sentence, we like to put information that helps the listener to understand the situation, at the beginning. This is usually information about times or places. So at the beginning of a new piece of writing you are very likely to see sentences that begin like this:

• In nineteenth century England ...
• In The USA ....
• At the beginning of the second world war ...

When we have a sentence like A cafe is on the corner this sentence is difficult for the listener to process. Why? Well the part a cafe is new information here. We know this is the first time we talked about the cafe because we said a cafe and not the cafe. Because of this we are more likely to use an existential construction. We are more likely to use a sentence with There is or There were. The word there doesn't mean anything, so there is no new information at the beginning of the sentence. I instead the cafe and corner both come at the end of the sentence where they are easy to understand, easy to process.

Notice that if we talked about the cafe before, then the Original Poster's example is better:

• The cafe's on the corner.

This sounds much better because we know which cafe we are talking about. We are not introducing something new at the beginning of the sentence.

So if we want to say a cafe is on the corner how can we say it to make it easier to listen to, easier to process? There are two options. We can use an existential construction:

• There's a cafe on the corner.

Or we can use SUBJECT COMPLEMENT INVERSION. This is when we put the Complement of the verb BE at the beginning of the sentence and we put the Subject of the sentence after the verb. Usually when we do this, the Complement gives us information about locations or times. Look at the sentence:

• A cafe is on the corner.

Here the subject is of the verb BE is a cafe, the Locative Complement ( - the complement which tells us about the location of the cafe) is on the corner. If we use Subject Compelement inversion then we get this sentence:

• On the corner is a cafe.

This sentence is also good.

The Original Poster's Question

A cafe is on the corner is not a good sentence in English, although it is perfectly grammatical. The reason is that it puts new information that we haven't talked about yet at the beginning of the sentence. We can make the sentence better by putting the locative complement at the beginning. (Locative Complements are easy for listeners to understand.) Alternatively we can use an existential construction:

• On the corner is a cafe.
• There is a cafe on the corner.

Notice that usually when we use an existential construction, the noun that we are interested in is new information. Existential sentences with noun phrases beginning with the are quite rare. This is because we like to use the existential construction to make new information easy to process.

Hope this is helpful!

Answer 3

I agree with δοῦλος' excellent answer.

If you have not already discussed the café, both choices in the original post are acceptable English. "There is a café at the corner" sounds more natural to my (American) ear than "A café is at the corner". If speaking informally, "There's a café at the corner" sounds even more natural than "There is a café at the corner".

If both the speaker and the listener already know about the café, the second choice becomes "The café is at the corner". If the purpose of the conversation was to locate either the café or the corner, "The café is at the corner" is more natural than "There's a café at the corner".

If the purpose of the conversation is to discuss something special about the café, and if the feature of the café is mentioned in the same sentence, the sentence can start with "The corner café" or "There's a café at the corner". For example:

• The corner café sells Tosci's ice cream.
• The café at the corner sells Tosci's ice cream.
• There's a café at the corner that sells Tosci's ice cream.
• Of course the café on Lexington Square sells Tosci's ice cream -- it's Tosci's!

Answer 4

AT is usually used for specific places or locations: places that are unique in some special way.

"I am at the train-station"
"I am at home"
"I am at a café"
(These examples are opposed to the street corner, which is one of many street corners)

The preposition "at" refers to your absolute location, which means that it does not indicate where you are inside of the place, only that you are there.

Now when we are referring to relative location we use ON or IN. Where is the person in relation to the location in question? Certain places are by definition relative and not "special" like your home or a train station. Examples include the

my couch (" I am on my couch at home ")
5th floor (" I am on the fifth floor " )
Building (" I am in a building " )
Street corner (" I am on the street corner in front of the cafe ")
