Mrs. Knott's Chicken Dinner Restaurant reopened Thursday night after its permit was restored following treatment for a cockroach infestation, theme park officials said.
Jason Soyster, a spokesman for Knott's Berry Farm, referred to the infestation as an "isolated structural incident" and said the restaurant was reopened at about 9:30 p.m.
The eatery had its permit suspended at about 2 p.m.
"The issue was contained to utility areas and had no impact on food preparation or guest dining areas," Soyster said. "Knott's remains committed to delivering safe, enjoyable experiences at all of its attractions, shopping and dining locations."
Deanne Thompson, spokeswoman for Orange County Health Care Agency, had said earlier in the day that the permit would be restored after the restaurant, on the grounds of Knott's Berry Farm, exterminated the cockroaches.
"There was evidence of an infestation and it was enough to suspend the permit," Thompson said.
The examination was part of a routine inspection, Thompson said.
Mrs. Knott's Chicken Dinner Restaurant, at 8039 Beach Blvd., advertises its chicken dinners, lighter-than-air biscuits and boysenberry pies on the theme park's website.
