The address of the restaurant Rachel (Meghan Markle) gives Mike (Patrick J. Adams) - 652 Columbus Ave - is the address of a KFC.
Harvey's (Gabriel Macht) wrist watch is a Patek Philippe 5004P Platinum Perpetual Calendar Split Second Chronograph watch, the real thing currently sells for over $270,000. This is over twice the cost of the Tesla Roadster Sport that he covets at the Gotham Car Club.
Harvey's (Gabriel Macht) style is reminiscent of James Bond. He often wears suits designed by Tom Ford, who also designs suits for James Bond. In this scene he is wearing a Patek Philippe watch and you can see an Aston Martin in the background, two more things that have been associated with James Bond.
In the scene where Harvey (Gabriel Macht) is discussing the Tesla Roadster with the concierge, the other cars shown in the shot are the AC Cobra to the right, a 1958 Jaguar XK150 to the left and the Ferrari 599 GTB Fiorano in the front.
After Harvey (Gabriel Macht) gives Laurence (Matt Cooke) the Tesla, the car Harvey drives off in is a 1967 Ford Mustang GT.
