Yes that website is good but unfortunately it is a commercial website and requires you to get a paid membership to access to some sections.

Long time ago Turkishonline.com was the leading website on Turkish as a foreign language but now it has dropped to second rank since a free website that you know well has taken the lead.

As I said it is a good website but there are tiny mistakes as well. I had a quick look on that particular dialogue that was linked to.

"Biraz da üzüm almak isterim."
This sentence is incorrect. It should be:
"Biraz da üzüm almak istiyorum."

And you can find another little files at
