Catch the continental breakfast at your hotel on your interview day. Most medical schools do not serve breakfast, and it may be a while before you are served lunch. Eating breakfast will also help you to wake up and have a clear mind for your interviews.
Another tip: Do not complain about the lunch you are served at your interview.
If you have specific restrictions (e.g., kosher, vegetarian, etc.), then be sure to notify the medical school at least one week prior to your interview day. Many schools have their lunches catered and must place their orders several days in advance.
