Very nice. I like the layout and styling very much.
The only problem I see is with the red text on the blue background. It is very difficult to read. I would suggest changing that. Otherwise, it looks great.
Also, you have one validation error, a minor one. In your
meta tag, you should change the & to & to be properly validated.
Looks good, I have to admit that the side menu moving around to reveal the sub menu items
a) really REALLY neat
b) a little bit tough to use, if I drrag my mouse striaght down the list I can't get past About Us without it sliding open to reveal the sub menus. Which of course means that I then have to wait for it to open and then drag my mouse to the new position of the "Information" menu.
