Chrome: Feedly is one of the best alternatives to Google Reader, but it doesn't really have the same look and feel as Google Reader. Feedly Reader is a Chrome extension that makes Feedly look just a bit more like Google's version.
With Feedly Reader installed, the sidebar and article display look a lot more like Google Reader than Feedly's default look. The colours are similar to Google Reader, and the basic navigation is as well. It's not an exact replica, but if Feedly's your go-to RSS reader with the upcoming demise of Google Reader, Feedly Reader is worth checking out.
