Wedding beer

I have been asked by my sister to make a batch or two of homebrew for her to serve at her wedding. The question is, what should I make? I'd like a beer that I will enjoy myself but that usually don't tend to be something that the masses will also like. I don't want to be selfish but I know if I make a beer to suit my tastes that the bride and groom will also enjoy it as we have similar tastes. I guess this changes the question to, is making a beer for a wedding more for the bride and groom to enjoy or the people attending? Maybe I will just make two.
