As it so happens, everything old is new again as apparently, all different versions of this drink are making a come back. This one is featured a few places on the internet - and I'll link to another version below it.
Don't feel like making one yourself? You can order coffee soda online - even the old favorite from 1895 - still available from Manhattan Special - the Espresso Soda and they have a decaf and sugar free version now too.
3 c cold coffee, double strength
1 T sugar
1 c half-and-half
1 pint ice cream
3/4 c club soda, cold
whipped cream for garnish
Another version recipe available here from Good Housekeeping
