Changes are in the wind at Station Square, the South Side entertainment spot that will be adding a new nightclub, two new office tenants and another restaurant this year.

The new nightclub will be called Zen and will be located in the Freight House Shops in space once occupied by the Palm Bar and Crawford Grill. It will be run by the owners of Privilege Ultralounge in the Strip District and is expected to open in the spring.

It is billed as a luxurious multilevel upscale nightclub with an Asian theme, and imagery and decor from the Far East.

Alcatel-Lucent, a global communications solutions and servicing company, will move this year from other Pittsburgh area locations into 36,953 square feet of space in Commerce Court, the seven-story office building Station Square owner Forest City Enterprises acquired last February,

Also, as announced last month, CardWorks, which services credit, debit and prefunded cards and other such products, will move from Smithfield Street, Downtown, into 57,511 square feet in Commerce Court.

Aided by $468,000 in state aid, CardWorks is planning a $1.8 million state-of-the-art facility at Station Square. It had the option of moving from Pittsburgh to another office in Woodbury, N.Y.

Both companies are expected to be in the building in the fall.

Since acquiring Commerce Court last year, Forest City has boosted the occupancy from 67 percent to 92 percent.

Also, GSP Consulting, which has offices in the Landmark Building, has signed a new seven-year lease and will be expanding from 6,100 square feet on two floors to 11,480 square feet on the fifth floor.

Separately, Island Cafe, a restaurant that features American and Greek fare, will open this month in vacant space next to Starbucks in Bessemer Court. It will serve breakfast, lunch and dinner. Val's Pizza, a pizza and pasta eatery, opened in the Freight House Shops food court in December. Both are owned by the Liadis family. They also have eateries in PPG Place and U.S. Steel Tower.
