Maggiano’s Little Italy in Washington, D.C., issued an apology on Facebook Monday after hosting an alt-right, white nationalist event over the weekend.
Participants praised Adolf Hitler and posed for pictures while making Nazi salutes and proclamations such as, "Hail Victory!"
The Friday night dinner, which was sponsored by the white nationalist organization, the National Policy Institute, was held to celebrate President-elect Donald Trump's victory, according to the Washington Post.
Protestors reportedly tried to confront those entering the dinner party but were quickly forced out of the restaurant by police.
Monday, Maggiano's released a statement on Facebook saying the Friendship Heights location was the "inadvertent site" of the protest and closed to protect the safety of its customers and employees.
"The protesters were upset because of a banquet we were hosting for a group called the National Policy Institute (NPI)," the restaurant said on Facebook. "This was a last minute booking made Friday afternoon, and the reservation was made under a different name, therefore we were not aware that NPI was dining with us or what the group represents."
The restaurant noted that after the event, an attendee tweeted out a photo of herself and others making a "Sieg Heil salute” in support of Hitler.
"This expression of support of Hitler is extremely offensive to us, as our restaurant is home to Teammates and Guests of every race, religion and cultural background," the statement said.
Lastly, Maggiano's said it will donate the $10,000 it made in sales Friday night to the Anti-Defamation League.
