I think you should go with more. Even simple stuff like a veggie tray, a cheese/cracker/pepperoni tray, and maybe even a fruit tray. Just so people have a variety to choose from. A couple different desserts (cookies/brownies, etc) are good also, especially for people who don't like cake.
When I have a get together/party I always try to have alot of apps/desserts, etc.
