Waldorf-Astoria Hotel
Schwartz's Toast of the Town evening will begin at 6:00 p.m. with a reception in Bull and Bear, named for the statues that graced the original Waldorf Bar where many famous drinks were created - the Bronx Cocktail, the Bobbie Burns and the Rob Roy.
Wine Magazine (December 2004)
The Rob Roy, according to The Old Waldorf-Astoria Bar Book by Albert Stevens Crockett, was named after a Broadway show of the same name, so it's possible that it dates back to around 1894 when Rob Roy, the operetta by Reginald De Koven, opened in Manhattan.

(Not dated. The New-York Historical Society has this listed as 1895-14D. It's certainly later than 1895 - the Bronx cocktail is here - but it's probably before 1910 -- ed.)
