Ron, whose real name is Rohit Mehta, is the owner of Ron's Coffee in New York City. The shop was frequented by Elliot for a time. The quality of the shop's Wi-Fi made Elliot curious, this lead Elliot to hack Ron, where he discovered that Ron had been running a child pornography website on the shop's bandwidth. Elliot anonymously gave a tip to the authorities, and Ron was arrested.
The real-life location of the coffee shop is Think Coffee on 4th Ave (between 12th and 13th Streets). Ironically, the real-world shop has no Wi-Fi, according to its website.
