A weekend fire has caused a Lehigh Valley restaurant to close until further notice.

Williams Family Restaurant announced the closure early Monday at 3630 William Penn Highway in Palmer Township. The Palmer Municipal Fire Department responded to the fire Sunday night.

“This has been an incredibly difficult and unexpected situation for us, and we are still processing everything that has happened,” the restaurant announcement said. “Our restaurant is more than just a business to us — it’s a place where we have welcomed friends, families, and wonderful customers who have become part of our extended family. We are so grateful for your continued support, kindness, and understanding during this challenging time.”

Firefighters were dispatched to the restaurant just after 10:30 p.m., according to the Northeast Bravest Facebook page.

According to a GoFundMe page set up to assist the restaurant’s staff, a grease fire started in the restaurant kitchen and caused structural damage. The fundraiser, intended to support workers while they’re out of work, has raised nearly $1,400 as of Monday morning.

“This fundraiser is for the servers, coworkers, and families who depend on those shifts and tips,” the GoFundMe page said. “What should be a season of warmth and celebration has suddenly become a time of stress and uncertainty for the people who count on this job to get by.”

On its Facebook page, the restaurant said it hoped to reopen soon.

“Although we may be temporarily closed, we hope to come back stronger and welcome you through our doors again soon,” the post read.
