My elderly mother is very ill and barely eating. We are trying to satisfy her cravings but I am stumped with this one. I think she is remembering No-Cal chocolate soda, which she used to drink years ago. Now I need to find a chocolate carbonated beverage.....preferably one WITH calories. Anyone know of names of brands or where to buy them in Manhattan? Short of that....where can I get a good egg cream to take out? Thanks so much.
