I'm with both of you guys. I hadn't thought of a chocolate ice cream soda for ages and now there it is in my mind, tempting me. This is something you just pretty much can't buy these days as far as I know. Of course they could be made at home, but it's hard to find vanilla ice cream that is quite as creamy and rich as I remember. And I don't know whether that chocolate syrup was just like Hershey's, maybe it was. The whipped cream was not like home-made, not as I remember it, either... It just got better as it melted together, the rich ice cream flavoring the soda, you'd use a long spoon to eat some of the ice cream and then take a long pull on the straw for the chocolate at the bottom. Mmmm.
You CAN make a decent root beer float at home but I haven't done that in years either.
And the worst thing is what has become of chocolate milkshakes. I used to go to High's Ice Cream parlor just for a milkshake. Nowadays people who eat at fast food franchises THINK they are getting milkshakes. Let me tell you something. I saw, on the curb, a MacDonald's milkshake that someone had dropped a day or two earlier. I don't know what those things are made of, but it was still kind of solid, a zombie milkshake. Like it had sawdust in it or powdered oatmeal or something. Yeeesh. The gentle creamy texture of one of those old milkshakes is nothing at all like what you get with your Big Mac.
