question on restaurants

[Noodle]

I have a question that I have not seen a clear answer to. My instructor advised our class that any restaurant that serves alcohol on the premises is off limit for conceal carry. However, the SC laws I have read only refer to establishments that obtain anymore than 50% of their revenue from alcohol are off limits. Of course I can understand not carrying into a bar or club, but would somewhere like Ruby Tuesday's, TGIFriday's, etc be off limits

Well nevermind, I see other posts that answer my question.
