Hallo Mr. Stefek
I thought You will be able to make a perfekt site on the third try.

But maybe You need some more

I like Your graphics, they look really funny. But I don´t like the style of 2 pages in the site.
First Gästebuch - what is the meaning of this different margins left and right? - Just set it to centered.
Second - at least the page Öffnungszeiten should be centered - this would look much better
And I don´t like Außerhalb in "Anfahrt" - this must be
außerhalb.
Therefore I´ll give You 8 out of 10 points.
