Restore PDF to Evernote service in Lion
This was a commonly discussed issue on the Evernote message boards when Lion debuted.  I've seen all sorts of "fixes" including hacking an old version of Evernote.  Fortunately, there's a much easier option.


Print something
Choose "Edit Menu..." from the PDF menu in the Print dialog
Click the "+" button then navigate to Evernote, highlight it and click "Choose"
You will now have an option called "Evernote" in the PDF menu in all of your system print dialogs.  Choosing this option will print to pdf, and open that pdf in a new note in Evernote.


This process has been tested on 10.7.2 with Evernote 3.0.5.

I hope this is helpful.
