Look and feel:
Nice site - simple, colourful and fun.
Information:
Exactly what your client and his/her customer needs - easy to find, concise information.
I say this having designed 3 such sites in the past.
Structure:
I'm seeing the same as knapper.
"order-gallery.html" seems a bit superfluous - why not link straight to "bouncy-castles.html" from the menu.
Code:
More use of <p> elements instead of <br /> in the content text would benefit anyone using a screen reader.
Overall, just the job.
I see I should have searched the forum before choosing my username
