However, leading up to the Google Reader shutdown users were encouraged to go to Google Takeout and retrieve their Google Reader data before it is deleted from Google's servers.
After checking the Google Reader page today, I discovered that users can still retrieve their Google Reader data before July 15th, when it really will be permanently deleted.
So if you haven't gotten your data yet or just want to take it anyways, click here. If you are looking for another RSS service to migrate to, I personally use and recommend feedly.
