When I was growing up, the soda pop was in these metal coolers and the bottles (yes, real glass bottles) hung from this grid. You put in your coin (a dime, I think) and it would release this lever and you could pull your bottle through. The front of the case had the bottle opener. I really miss vended soda in a bottle. Yeah, you can get a few of them in specialty stores, but they're not all available and none are vended this way any more.
I miss the lunch counter at the local pharmacy where I grew up. There was a real soda jerk and I would be able to ask for extra syrup in my sodas. The ice cream was real and homemade. I could get all sorts of creamy and cold desserts made to order right in front of me. Root beer was the best. A cold root beer with an extra shot of syrup. So sweet!
ETA: Oh, another store in town (the Murphy's Five and Dime, I think) had an AUTOMAT. It was left over from the 50's, I think, because I never saw them any other place. They weren't popular anymore, I don't think. I loved it, though. It makes me long for those earlier days.
(I guess these aren't actual foods, but are food related. Sorry.)
