Interview at Golden Corral on Thursday!?

I have never held a job before, besides small babysitting things for my cousins! So I dont really have a resume to bring? So what DO I bring? This will also be my first interview. I already know what to wear, but could anyone give me tips on what to bring and how to best answer some questions. I dont even know what kind of questions a buffet like this asks. Help please! Thank you in advance :)
