The Shack Hometown Grill shut its doors recently after almost three years at the corner of Post and North Pine Creek roads.

The 160-seat restaurant with over 40 workers closed because business was insufficient, said Tommy Febbraio, a commercial real estate broker who co-owns the property with Westport lawyer Tom Sargent.

"We'll miss The Shack. They catered to a lot of Fairfield families," said Febbraio, who himself operates several restaurants in the area and had co-owned the restaurant Sidetracks at the site with Sargent for 22 years. "Another restaurant's departure is another restaurant's opportunity."

Ten restaurant groups from New York City to Boston have shown interest in leasing the 4,400-square-foot space, which has a patio that can accommodate 20 additional seats, Febbraio said.

"It's a great location," he said.

The Shack's co-owners, who included Greenwich restaurateurs Walter Miller and Phil DiStefano, first operated Beach Cafe at the property for a few years after Sidetracks closed. They then opened The Shack in March 2010, Sargent said.

"I'm sorry they could not make it there," he said. "They closed suddenly."

Miller and DiStefano also co-own Greenwich eateries Beach House Cafe and Sundown Salloon.

The property at 2070 Post Road has a decades-long history as home to restaurants. Before Sidetracks, it was the site of Dogwoods from 1979 to 1984 and Acropolis before that.; 203-255-4561, ext. 112;
