FedNuts Chicken Sandwiches Head to Center City for One Day Only; Chef Shuffles at Mainland Inn

CENTER CITY — For one day only at their Center City shop, Federal Donuts will serve their coveted fried chicken sandwich, typically available only at Port FedNuts at Spruce Street Harbor Park. The sandwich ($7) will be available beginning at 11 a.m. on Thursday, June 4, until 7 p.m. — unless they run out before then, and it seems safe to assume that they will sell out quickly regardless of how many hundreds they're able to make.
