Surveillance video shows the suspects going into a dining room, storage room and office at the golf course, where they stole four flat screen TVs, two speakers and 13 bottles of wine.
The first suspect is described as about 20 years old. He was dressed in all black and wore black gloves and red and white stocking cap.
The second suspect is said to be about 40 years old with gray, curly hair and a mustache. He was wearing jeans, a gray jacket, an Oakland Raiders "24" jersey and was seen smoking a cigarette at the scene.
The men arrived and left in white van. It has windows on the passenger side, but none on the driver's side. There also appears to be some writing or an emblem on the passenger quarter panel and both front doors.
Anyone with information on the suspects is asked to contact Grapevine police at 817-410-3200.
