Bo Blair — Washington’s restaurateur to the millennials — is busy.

Blair owns 20 restaurants, bakeries, bars and assorted entertainment properties from Washington to the island of Nantucket, which is his habitat of choice.

Most of the action is currently in Washington, his hometown.

Aside from hosting the NHL Spectator Plaza at the Fairgrounds across from Nationals Park during the league’s Winter Classic on Jan. 1, he recently opened his fifth Jetties sandwich shop, this one located on Connecticut Avenue NW, just south of Chevy Chase Circle.

The other Jetties locations are in the District’s Foxhall and Macomb neighborhoods; Bethesda; and downtown D.C. A sixth location is to open this spring in the Penn Quarter.

“We are trying to expand our existing fast-casual concepts carefully into top locations that serve our clientele and introduce us to new customers,” Blair said. “New fast-casual restaurants are opening every week, and we have to stand out.”

Blair is opening his second Surfside restaurant, called Surfside Dupont, Jan. 6.

He has a new southern concept — called Due South — coming to the Lumbershed Building at the Navy Yard in May of 2015. Rusty Holman, from Blair’s Bayou music restaurant/bar, will be the executive chef. The eclectic menu is to include fare inspired by places such as Charleston, S.C.; North Carolina; Texas; and Louisiana.

Finally, Blair is close to signing a lease for a second Millie’s, which will be located in Spring Valley near the American University School of Law. Around 40 families that are close to the entrepreneur have loaned Blair $25,000 each to get the District Millie’s going.

The original Millie’s is in Nantucket.
