The Hearth & Hound, the Hollywood restaurant opened by the chef April Bloomfield and the restaurateur Ken Friedman in 2017, closed after dinner service on Saturday night. Ms. Bloomfield, who made the announcement on the restaurant’s Instagram account, had acquired Mr. Friedman’s share of the Hearth & Hound last June, when their decade-long partnership was dissolved in the wake of the sexual harassment scandal that engulfed the business.

Ms. Bloomfield posted the announcement as dinner guests were still ordering, and offered no reason for the closing. The post showed pictures of her and smiling employees, who number nearly 100. “I’m so proud of what we accomplished in our short time,” she wrote. (The restaurant was open for just 15 months.) “I thank our guests, friends and supporters for the warm welcome during a tumultuous last year.”

Ms. Bloomfield did not respond to phone calls and text messages seeking further comment, and declined to speak to a reporter who approached her during dinner service on Saturday.

The large restaurant was packed, inside in the dining room and bar, and outside on the patio. Fires were still blazing in the open kitchen, where Ms. Bloomfield was cooking in a blue shirt and apron. She paused occasionally to greet regulars; as diners hugged her, she teared up and wiped her eyes.
