Multiple editors for website

Hey guys.

I need to design a website where multiple clients can log into and edit their specific page and not see or be able to edit other pages.

Example: A website that promotes restaurants in a specific area. Each owner of a restaurant has their own page on the website and need to edit that page only.

Is there a plugin that allows multiple users to log in and only edit/post a specific page/section of the website?

Thanks in advance!
