"daqui" is joined the preposition "de" and adverb "aqui", it means " de + aqui =daqui". We can translate lake this : Aqui =here. Daqui = from here or from... to.

Yes the sentence "there's a great restaurant near here" is right. In my first comment i translated directly, and i don't know how to edit the comments.

Thanks guys. Antonio, the explanation was perfect - I understand now.

I will try explain. "Daqui is always used to indicate a localization, because of this you have to use another word to complement, like "near". "Perto daqui" is like "near from here", from location that where you are. "Aqui" is "on here", the exact location that where you are. I hope that you can understand.
