The most tastiest poll in the biz!

What kind of cookies should I make for an event tomorrow night? I am a pretty great baker (if I do say so myself) and would be willing to try new recipes. However, it's for 20-30 adults, so a crowd-pleaser and something not-too-pricey (ie. let's leave out walnuts, macadamia nuts, and truffle salt, and saffron) would be the good.

Obviously I feel like chocolate chip is the safe bet. Or I'm toying with making an oatmeal cookie base and dividing it so some have chocolate chips, make one a spice, and the the other something else?!? Lemme know!
