The food court will have a Subway by late June, Rosen said.
A TCBY opened there April 1, she said.
Other recent additions are Children's Place, a children's clothing store, Stride Rite Family Footwear, a children's and adult shoe store, and Harry and David, a specialty food and gift store, Rosen said.
Children's Place opened at the end of February in building 6. Stride Rite Family Footwear opened next door at the beginning of March. Harry and David opened at the end of March in building 1.
The village-style outlet center, owned by Baltimore-based Prime Retail, opened with 51 stores in its 218,000-square-foot first phase in August 1998.
The center grew to 76 stores when the 100,000-square-foot second phase opened in November.
There are now more than 80 stores, with a 100,000-square-foot third phase slated to be built, according to Rosen.
The company has applied for a permit for construction of the third phase but needs site plan approval, according to the county's permits and inspections department.
Rosen said she expects to make an announcement about the third phase soon.
The outlet center got a new general manager this week, Rosen said.
Nancy Brown, who was manager at Prime Outlets at Perryville, Md., started Tuesday, she said.
Brown replaces former manager Gill Brooker, who left the company earlier this year, said Rosen, who handled the job in the interim.
