Via Gothamist, here’s more information about the cute guy who played the bellhop on the season premiere of Mad Men: his name is Orestes Arcuni.
Also via that Gothamist post, here’s a long radio interview with him and here’s an interview with Bryan Batt (Sal) in which he talks more about his character.
And if you really love Mad Men, Vanity Fair has an extensive piece on the show, including a visit to the set and an interview with Matthew Weiner.
