My daughter is visiting from Walla Walla WA where several gas stations/burger joints/restaurants serve a drink called a Scotch & Soda. From what she can gather, it is typically made with a citrus soda (7Up / Sprite), lemon / lime juice, and vanilla syrup and served over ice and is non-alcoholic. Some say that the "Scotch" part comes from a shortening of Butterscotch. She is totally obsessed with this drink but has had trouble finding the origins and history or anything else about the drink. In fact the majority of people, even in Walla Walla, haven't heard of it. Also, she is not interested in hearing that "a non-alcoholic scotch and soda is technically just soda" because she's heard that already and she finds it condescending and irritating!
