Welcome to the Q&A Forum

So your assertion that because we bring in some content from FourSquare (note through their API not by "scrapping" it) that we aren't providing value is really off the mark. It is not about value.  It is what google sees as duplicate content that is available on many sites.    Google is demoting or filtering lots of pages that have content available on other websites. Yelp and Urbanspoon might get away with it because they are more powerful than other websites. I know that you don't like my answer.   I am telling you why I believe your traffic is down. Here is a big reason.   Your site is showing lots of duplicate content.
