I don't really find anything wrong with the banner. It doesn't give you an overwhelming visual image of what INX would be, I'd hope you have a generla idea if you're aldreay at the site. MY only beef with is is al the white.

The overal design is very light. I'd ike to see some darker spot to draw the viewer's eye towards the imporatn parts. For instance the name in the banner. The top left of the banner itself blends right into the bg tile, and the lettering has white a stoke. I'd add either a small black stroke otuside the white (small as possible) to keep it seperate from the back. the banner and tile blend together, I'd try to keep the name seperate and fresh for people to see.

I'd do a little tweaking to the menu. The style is good, and it fits nicely, but it looks too big. I'd either crop off the height (just make it shorter) or pump the fot size up a little just top use up some of that extra space.
Again, that's just my opinion.

Other than that, 'd just get some hyperlinks working in there.
