Renzo Serafini - definitely the Locarno at 31 Academy Street.
Dorandos had a confectioners and tobacconists shop at 36 Church Street (down from Fraser's Auction Rooms). Was the man who owned this shop related to Henry who ran Dorando's Cafe at 89 Academy Street ?
Caley 100 answered that in an earlier post. It was his brother, Bianco. A lovely man who made "fudge" that tasted just like I remember my grandmother making 50 years ago. I blame her for the state of my teeth today.
