What food to make for a Doctor Who party?

So, for the 50th anniversary, we're having some friends over to watch Doctor Who, and I want to make some themed food. So far, my mom wants to make broccoli cheese soup for the main dish, (so boring...) but she said we can most likely get fish fingers and custard. I also want to decorate sugar cookies with stuff Doctor Who related. Maybe some bow-ties or 3D glasses, and cute phrases like, "Hello Sweetie," "Wibbly wobbly," and "You're Dalek-table" I need more ideas though! The people coming over are major Dr. Who fans. Any ideas? maybe drink ideas, or easy decorations?
