CHICAGO—The East Loop has sometimes suffered in comparison withthe hot neighborhoods of River North and the West Loop, butGlenStar Properties, LLC just signed a significantlease in the submarket with a sought-after tenant.

Punchkick Interactive, Inc., a mobile marketingexpert, will occupy 23,401-square-feet at GlenStar's 55 East Monroebuilding. The fact that Punchkick was a River North firm could be asign that amenities like Millennium Park and the growing popularityof the submarket as a residential neighborhood are attracting moreoffice workers to this side of the CBD. The firm will make the movefrom 22 West Ontario St. later this year.

“Punchkick is representative of high growth potential technologytenants that landlords covet,” said GlenStar managing directorChristian Domin, in a prepared statement. He wasnot available by press time, but GlobeSt.com will post an update onMonday. “As these newer firms mature they come to a point whereadditional resources, access to amenities and diversetransportation options become critical to sustaining operations andrecruiting a talented work force.”
