Memorizing the menu is part of the job, and the interviewer wants to hear that you are not daunted by the task! Start off by telling the interviewer that you look forward to learning the menu and will work diligently to learn the menu as quickly as possible. Next, mention a reasonable timeframe to learn the menu taking into consideration how many pages the menu entails. You might share that it will take you 1-2 weeks to learn the menu in its entirety. Finally, share your gameplan for learning the menu. You might mention that you will look at the big picture first recognizing categories. You might mention that you will make flashcards for yourself. Or, you might mention that your roommate has already volunteered to help you study.
