Late Night Cravings

During the summer, I am often out late at night going to a friend's house or somewhere else and I often pass by the Jack in the Box that is shown in this photograph. Every time I pass by at night, the drive-through is lined with cars. This photograph was taken at 11:30pm and outside the frame of this photo were three more cars lined up. The line can get so long that my friends actually avoid this Jack in the Box at night. I notice that in my area the only food places still open late at night are fast food chains. Why are there no places to eat healthier foods late at night? Is it because not many people opt to eat healthy late at this time?
