In other neighborhood news, Harvest (44 Brattle St. at Story Street) relaunches Sunday brunch from 11 a.m. until 4 p.m. on a heated patio. Eat eggs Benedict, pancakes, and crullers by a roaring fire.

Amid a slew of restaurant closings, a dash of hope? Instagram chef-sensation Salt Bae — formally known as Nusret Gökçe — has teased local fans with promises of a restaurant for months. And now the Turkish chef has taken to social media to announce that he will open Nusr-Et Boston, a steakhouse, this weekend (100 Arlington St. at Stuart Street).
The Globe has independently confirmed that he will indeed open his restaurant on Friday, Sept. 18, near Bay Village and the Back Bay (not Bae). Salt Bae made his name through viral Internet videos in which he slices and salts meat with dramatic flair. He currently has more than 30 million followers, as well as restaurants worldwide.
His restaurant replaces Nahita, which also served swanky steaks (and sashimi, tacos, and cocktails).
