Reply to House or Hip-Hop as a majority?

My first real gig is going to be at a local Bar on a busy Main strip in a college town here, blocks away from a state university. I frequently go out here, I know the crowds; I know the music. I know that the music choice is the bars discretion, and that's totally fine. Here's my question;

From your experience from the DJs here that have performed these types of gigs; should I focus primarily on popular, well known songs or dive into music I know to perform. I primarily play house, club and even my hip-hop songs are club mixes. I still have a plethra of popular hip hop songs and every so often I go into the billboard top club songs, but mostly everything I have is underground stuff. I just don't know what to expect. I have to present the general manager with a CD of a mix I believe the crowd will respond to. I KNOW I have the stuff to make the college crowd dance and get crazy, but I want to try to balance this with the approval of the manager.
