RE: Ice cream sodas these days?
When I was a kid visiting my grandparents in Elmira, NY, there was a ice cream place called Lovell's that made a "Lucky Monday".
It came in a special glass that Lovell's had made for them, sort of a big milk shake glass that flared out at the top into a sundae bowl. They would fill the glass with your favorite pop, then make a sundae in the bowl with hand scooped ice cream, syrup, whipped cream, etc. - as you ate the sundae, the ice cream and syrup wfell down into the pop, so that when you had finished your sundae, you had an ice cream soda.
