How to say where you buy something from


I'm working on noun modifying clauses so this sentence is a little basic.
However would `から` be the appropriate word to use to express that I have
bought something from a particular place. Where would it go in this sentence:

> これは、私が毎日コーヒーを買う、きっさてんです。




You can't use から in your sentence これは、私が毎日コーヒーを買う、きっさてんです(This is a cafe where
I buy a coffee everyday).

If you want to use から, you need to change the structure of the sentence like
私は、この喫茶店から毎日コーヒーを買う(I buy a coffee everyday from this cafe). However this
sentence is a bit unnatural and 喫茶店で is more natural. If you buy something
from someone, から is used but で isn't used like 私は彼から本を買った(I bought a book from
him).

That is to say, で買う means "buy at place", から買う means "buy from owner", so I
feel 喫茶店から買う is a bit unnatural because 喫茶店 is a place.
