CNN Films revisits a forgotten 9/11 casualty — the restaurant at the 'Top of the World'

Michael Lomonaco can account for every minute of the morning of Sept. 11, 2001 — including the small decision that saved his life.

Lomonaco, the executive chef who ran Windows on the World on the 106th and 107th floors of the North Tower of the World Trade Center, was on his way up to his office when he stopped at an optometrist shop on the ground level to have his eyeglass frames adjusted.

He was still inside when American Airlines Flight 11 hit the tower above him at 8:46 a.m.

"I felt the building shake," he recalled in the new CNN Films documentary "Top of the World." "And I thought that can't be the subway. That's impossible."

Lomonaco was evacuated. From the street, he watched employees of his own restaurant wave a white tablecloth from a window more than 100 floors up. In all, 79 Windows on the World employees and 91 guests died that morning in the gastronomic soul of the Twin Towers — the one part of the complex that belonged to New Yorkers who didn't work there, and to visitors from everywhere else.

"Top of the World" premiered Monday on CNN and is streaming on the network's subscription streaming platforms. The documentary short arrives on a double anniversary: 25 years since the attacks, and 50 years since Windows on the World opened on April 19, 1976.

It is the work of producer-director team Betsy West and Julie Cohen, who made "RBG," the Oscar-nominated portrait of the late Supreme Court Justice Ruth Bader Ginsburg. The film was inspired by Tom Roston's book "The Most Spectacular Restaurant in the World." Actor Denis Leary voices the restaurant's creator, Joe Baum, drawn from decades of archival recordings.

What emerges is a history of how a restaurant transformed the reputation of the monolithic Twin Towers, which received little respect from architecture critics and bafflement from a public that wondered why it was built in the 1970s by the Port Authority of New York and New Jersey as the city was fighting off financial collapse.

"This film tells a story of a restaurant that was very special to New York a time when New York was getting kicked in the teeth," the Brooklyn-born Lomonaco said in a recent interview.

The World Trade Center operators turned to restaurant impresario Joe Baum to create a dining experience that would draw people to the Manhattan neighborhood largely known for its blocks of stores that sold radios and electronic parts. Baum was known for such New York dining landmarks as the Four Seasons and Tavern on the Green, and his new creation became an immediate hit after it opened in 1976, becoming a magnet for tourists and celebrities alike who came for the eye-popping views through the floor-to-ceiling windows.

Lomonaco is a central character in the "Top of the World," as his arrival as the executive chef of Windows in 1997 boosted the restaurant's culinary reputation. A hot chef who oversaw a turnaround at the 21 Club, another legendary New York dining spot, Lomonaco turned Windows into a destination for American cuisine along with the breathtaking views.

Lomonaco and the restaurant's owners formed Windows of Hope, a charitable foundation that raised more than $22 million to pay for healthcare and tuition costs for the children of the victims. "We were giving checks to people to pay their rent before federal funds came through," he said.

Lomonaco said he still meets patrons who give him a matchbook or coaster from their visit to Windows. "They feel like they have to give me or send me these little artifacts," he said. "That's what has touched me the most."
