I've been in touch, over the past weeks with two descendants of Joseph Guffanti, the Italian restaurateur who ran a famous restaurant on Seventh Avenue and 29th from 1892 on. We're not sure when it closed, but it was probably sometime in the 1960s.
Neither relative had any of Guffanti's old recipes, alas, but one did send me a copy of the wine list. There's no date on it, but, judging from the prices, it hails from the 1950s or 1960s, when Guffanti's nephew Domenick Caserio and his sons were running the place. (Notice the "Casa Domenick on the cover page.") Looks like a pretty good wine list for a New York restaurant of that era, as well as a fine selection of cocktails and cordials.
