The team behind The Banks, Bistro du Midi, Grill 23, and Harvest have splashy plans for Boston’s Seaport. Himmel Hospitality Group will open Le Boulevard, a French bistro, and Bar 23, a smaller version of steakhouse Grill 23, in spring 2027.

While many national steak chains have settled in the Seaport in recent years — including the upcoming Hawksmoor and Maple & Ash — Himmel is locally owned.

Bar 23 (11 Fan Pier Blvd.) will be a cozy, 75-seat Grill 23 spinoff. Here, chef-partner Robert Sisca promises “ice-cold martinis” and a steak menu that echoes its Back Bay counterpart.

“We’ll have the steak trinity: Kobe, 100-day ribeye, and dry-aged sirloin,” says Sisca.

The formula works: Back Bay’s Grill 23 has stayed open since 1983.

Le Boulevard (10 Fan Pier Blvd.) will bea Parisian-inspired restaurant with 250 seats, including a big patio. Sisca has eyed the neighborhood for a French restaurant for years.

People in the Seaport are “looking for a great atmosphere, a good-looking venue, and something more fun,” Sisca says.

And something luxurious: He says that “steak frites will be huge,” with multiple varieties, along with Dover sole, escargot, and bouillabaisse.
