SUNNYVALE — Whole Foods market and AMC DINE-IN Sunnyvale 12 movie complex are providing a major boost to downtown Sunnyvale by launching operations and opening their doors this week in the CityLine Sunnyvale mixed-use complex.

The two merchants are the primary anchors of CityLine Sunnyvale, which has begun to dramatically reshape downtown Sunnyvale with new shops, restaurants, entertainment hubs, office buildings, and housing.

The CityLine Sunnyvale complex is being developed by STC Venture, which is a joint endeavor of Sares Regis Group of Northern California, a big homebuilder; and Hunter Properties, a major developer.

“We see both of these businesses as having a central and important place in what will be a vibrant, walkable neighborhood,” Deke Hunter, president of Hunter Storm, said of Whole Foods and the AMC movie theaters.

Whole Foods opened its doors Thursday while AMC is slated to begin operations on Friday.

The two primary anchors of CityLine Sunnyvale are in the same building at the corner of Murphy and McKinley avenues.

Whole Foods occupies 52,000 square feet on the ground floor of the building while AMC DINE-IN Sunnyvale 12 occupies 52,000 square feet on the second floor of the building.

“We hope that the opening of AMC Theatres in particular marks the beginning of bringing back public entertainment safely,” Hunter said.
