The official grand opening of Denver Union Station has been delayed until July 26 to allow all of the tenants in the landmark building to move in and begin business operations.

The ticketed Great Hall Gala scheduled for July 11 and a VIP Champagne Reception on July 12 will go on as scheduled, Union Station Alliance spokeswoman Julie Dunn said Wednesday.

Some restaurants and businesses will be open by July 12 or before. Others need more time to finish construction to open by the July 26 official grand opening.

“There are many different contractors in the building and many, many subcontractors,” said Walter Isenberg, chief executive of Sage Hospitality, a co-managing member of Union Station Alliance. “The complexity of the project is what has caused some of the delays.”

The 112-room Crawford Hotel, which occupies the upper floors of the former train station, will be fully operational starting July 12. Some restaurants will be open by July 12 but will not operate at full capacity until July 26. Others will open as their construction is completed, Isenberg said.

Chef Jennifer Jasinski’s Stoic & Genuine restaurant will open July 8. Restaurant spokesman John Imbergamo said the delayed opening of other businesses in the building should have little or no impact on Stoic & Genuine.

“We think the restaurant will be significant enough that the public will find us,” he said.

When Union Station fully opens, it will house 15 restaurants, bars and retailers.

Tattered Cover general manager Matt Miller said he doesn’t know when the book store will open.

The Kitchen Next Door restaurant will have non-public “soft openings” on July 8 and 9 then will open to the public July 12.

Isenberg said that in addition to Stoic & Genuine and Kitchen Next Door, restaurants and bars scheduled to open by July 12 include Acme Burger & Brat, Cooper Lounge, Milkbox Ice Creamery, Pigtrain Coffee, Snooze and Terminal Bar.
