A lot of the school was dank and dark. Lots of my grade school memories are lit only by weak light bulbs. In my memory the whole school was in a basement. Is it possible that much of it was only a single story and all my classes were underground? That seems strange so perhaps I just don't remember those well-lit upper stories.
The lunchroom was in a semi basement, halfway under ground, with windows near the low ceiling. Even as a kid those ceilings were low. I only have a couple fragments from that cafeteria.
1) We could buy ice cream treats for a pittance. My favorite (and still is when it comes to those sorts if treats) was the chocolate cookie crumble covered vanilla one on a stick.
3) In the back of the cafeteria was the lounge for the upper schoolers. I think we were allowed in there to use the vending machines but I'm not sure. The older girls would use it as their smoking lounge.
