What is the best way to memorize a vast amount of information?

I have to memorize an entire menu before my job orientation which is this coming saturday. I know I've messed up by procrastinating. I just started studying today, and I probably know 20% of the menu. The menu matrix that they've given me was probably around 30 pages, and I retyped it and simplified it as much as possible and the study guide I made is 9 pages. I need to know 100% of it before Saturday at 9:00 A.M. Help is appreciated! Thank you!
