It's no Dean & DeLuca but a division of Eat'n Park will operate a convenience store featuring a limited selection of prepared foods and fresh produce in the new PNC tower Downtown. Gary Saulson, director of corporate real estate for PNC Financial Services Group, confirmed Thursday that Parkhurst Dining Services, part of Eat'n Park Hospitality, will run the store in the lobby of the 33-story Tower at PNC Plaza.
