By "restricted" I assume you mean articles for which only the citation is displayed, or Google Scholar's (GS) link takes you to a website informing you that the article "is for subscribers only" or other such sentiments. If I've misinterpreted your question, apologies for the blather that follows....
Most scholarly journals want you (or your library) to subscribe to the journal before they will let you read full text. If you're affiliated with a college or university, I would suggest contacting them to see if you already have full-text access privileges through their library. Google tries to smooth the connection between GS and libraries via Library Links, but not all libraries participate in this service. Your library may require you to access the journal through their online catalog, for instance, rather than through GS.
If you don't have access privileges via a local library, you have a choice between convenience or cost. Obviously, you could subscribe to the journal, but that's likely to be fairly expensive. However, journals/databases also offer "independent researcher" access -- JSTOR is one example.[2]
There are also several companies offering "document delivery" services that will get the article for you. GS will sometimes have a "BL Direct" link -- you can pay the British Library for full-text access on a per-article basis. Ingenta Select boasts access to over 30,000 journals -- maybe they have yours.[3]
If saving money is a priority over speed, your local library may have a paper subscription to the journal. If they don't carry the journal, visiting in person may enable you to place an interlibrary loan request for the article, usually for free or low cost.
