Will I Be Able To Get A Job As A Waitress At Places Like Denny’s Or Shari’s Or Ihop?

I am seventeen years old, turning eighteen in July. I will have my high school diploma shortly and I have also done two years of college.
I have a job as a receptionist right now, so I have some customer service experience, but no actual waitressing experience. I am good with people, and I am nice, and I am cute (I have heard that matters for waitressing..)
I got the job because the original receptionist quit because of a sudden medical problem, so I had to learn the job quickly….so I am going to try to play up that I am a fast learner on my resume/cover letter. My boss likes me and she says she gets to leave earlier when I am there versus when the original receptionist was there.
So, what do you think? Can I be a waitress right away, or will I have to start as a hostess? How much more does a waitress get paid than a hostess? I am trying to make like 400 dollars a week (I live in Washington and we get 8 dollars for minimum wage plus tips)…Will I be able to? Thanks for any help.
