Is This A Good Idea?

I need a theme for my 13th birthday party coming up on the 10th of febuary. I did an online survey but only 2 of my friends have answered yet. My best friend said chocolate theme, is that a good idea? Like we can play games that have to do with chocolate, look up facts about chocolate, EAT chocolate( the best part!) and I even have a chocolate fountain and desert fondu machine. But there is one, small, problem. I have a friend who doesn`t like chocolate even though all the other ones LOVE it (including me!). Is it a good idea???
