5 Napkin Burger, the popular burger chain that’s opened three New York locations since 2003, has leased its fourth location at 150 East 14th Street, on the southwest corner of Third Avenue.

The restaurant includes 3,570 square feet of ground-floor space, as well as a full basement. Winick Realty Group LLC’s Tatiana Jung-Voevodina, along with her associate Richard Smith, director, represented 5 Napkin Burger. Building owner Solil Management was represented in-house by Judy Brener.

“This prime corner has laid fallow for the past five years," Jung-Voevodina says. "5 Napkin Burger will undertake a full reconstruction of the building and turn it into a wonderful gem."

5 Napkin Burger expects to open in April 2011. The location is in close proximity to bustling Union Square, as well as New York University, with its nearby dormitory buildings and the campus itself.

5 Napkin Burger will anchor the heavy-traffic block that includes next-door neighbor Trader Joe’s. The restaurant chain already operates units on Ninth Avenue in Hell’s Kitchen, Broadway and 84th Street on the Upper West Side, and in Astoria.
