Is voting like / dislike redundant if there is a in-depth rating feature?

I was approached by a site owner to expand a couple of feature on his existing site. The said site is a business directory and users get to vote like / dislike if the businesses are restaurants.

The owner would like to include an in-depth rating feature where users can rate the service, ambience, etc on a scale of 1 to 5 when they submit a review. At the same time, the owner wants to retain the like / dislike vote feature on the note that users can just vote like or dislike if they are 'lazy' to write a review and give ratings.

In the context of user experience, does having either one feature makes the other somewhat redundant?
