After three decades spent poking around Detroit for the right opportunity, Norm and Bonnie LePage of Griffin Claw Brewing Co. and Big Rock Chophouse in Birmingham are opening their first restaurant in the city and looking at locations for more.

Beacon Park anchor restaurant Lumen Detroit is expected to open the first week in April in the green space and concert venue near DTE Energy Co.'s headquarters in the heart of Detroit's central business district.

The 4,000-square-foot restaurant at 1903 Grand River Ave. seats 125 indoors. Sliding glass walls accordion out to the corners of the restaurant to mingle the dining room with a 150-seat outdoor patio in warmer weather.

A rooftop harbors an additional 45 seats, views of the city and a sustainable plant bed surrounding the dining area.

The husband-and-wife team own and operate Lumen with their son Scott LePage and his wife Susanne. The family also operates Clubhouse BFD in Rochester Hills, Big Rock Chophouse and Griffin Claw Brewing Co. in Birmingham and an incoming Griffin Claw in Rochester Hills.

They hired Sarah Stricher as Lumen's general manager and William Hollie as kitchen manager, and worked with Big Rock Chophouse Executive Chef Gabby Milton on the menu.

Beacon Park is a 1.5-acre green space on Cass and Grand River avenues. Its operator, Downtown Detroit Partnership, hosts concerts, movie nights, pub nights and other events there. DTE developed the park with the intention of creating a "beacon" for the surrounding community and for downtown development to spread northwest along Grand River Avenue.

The LePages have been involved in the development conversation, including sitting in on meetings with nearby business owners to discuss the northwest downtown's future, Norm LePage said.

"We're committed to this area," he said. "(DTE) has hit it out of the park. We just want to be a part of that."

Norm LePage said he and his wife came close to opening a restaurant in Detroit's Midtown in the last couple years. They had been visiting the city weekly or monthly for decades seeking the right spot.

They finally said yes when DTE came looking for a vendor for its community park concept. The park was first announced in 2015 and DTE announced it chose the LePages in May 2017.

Now Lumen's opening is looming and Norm is readying for what's next. He said he has already "identified locations in this area for our next move." Some of the two or three sites in discussion — but not all — are within eyesight of Lumen. He declined to offer more location details and said nothing specific was decided, but he did tease: "Maybe food and brewery, who knows."
