Two separate vendors at Charleston International Airport will spend almost $10 million collectively in new retail and restaurant space.

The investment is in addition to the $189 million the Charleston County Aviation Authority is shelling out to totally redo the 29-year-old terminal, said Rob Carew, director of airport properties.

Buffalo, N.Y.-based Delaware North Co., a 100-year-old, family-owned hospitality and food service company, plans to invest about $6.5 million in new facilities, while Hudson Group will spend close to $3.3 million in new retail outlets.

The two firms recently signed 10-year contracts to operate at the state's busiest airport.

Among the well-known national and Lowcountry brands coming to the airport via Delaware North are Caviar & Bananas, Wendy's, Charleston Beer Works and DeSano Pizza Bakery and Bar.

Also on the menu are Harvest and Grounds Bakery & Coffee, which will feature Charleston-based gourmet coffee roaster King Bean Coffee Roasters, and Jack Nicklaus Golden Bear Grill. Coincidentally, Nicklaus is a partner in the DeSano Pizza chain.

On the retail side, Hudson Group will offer Eddie Bauer, Lowcountry Harley-Davidson, Dunkin Donuts, Tech on the Go, Discover Charleston gift shop and Veranda News, the latter in partnership with Saffron Cafe & Bakery of Charleston.

The terminal building is only a few months into its massive overhaul, so it will be a while before spaces for the new vendors will be available for them to upfit, Carew said.

Some of them could be finished along with the terminal redevelopment and expansion, which is set for completion in August 2015, but maybe not all of them.

"It will depend on when the shell of the spaces will be completed," Carew said.

Work should begin on some of them by the end of year, he added.

Temporary kiosks could go up for some while construction is underway.

Airport officials plan to move more restaurants and shops beyond the security checkpoints, but some retail outlets will remain in the unrestricted public area in the redesigned terminal.

Aviation Authority attorney Arnold Goodstein said the agency recently concluded negotiations with Delaware North, a new vendor for the airport. Hudson Group was already operating there.
