Unfortunately, no suggestions for really good websites. Why don't you browse some colleges and universities. I'm not saying they are good - but they will probably have some nice sites that are menu-oriented.
I offer a word of encouragement. Visiting a bunch of different sites often leads to inspiration. So you have the right idea.
I've heard various discussions with our web site designers. I won't tell you to visit our site - because you probably cannot. It is .MIL site that requires a government smart-card to get in.
