It was a hell of a halftime show.

Some two dozen fans of Notre Dame football were watching the Fighting Irish game on TV at Connolly’s in Times Square when the three-story watering hole filled with smoke from a kitchen blaze.

“We ran for it,’’ said Dorothy Zalomski. “I still had my beer in my hand.’’

“I’m glad no one got hurt,’’ said patron Michael Farley, who watched the remainder of the game at a nearby pub, O’Brien’s, a block away. “I’m glad it happened at halftime, too.’’

Passerby Amy Balessandro of New Jersey, said, “Oh man, seeing Hazmat vans right off Times Square … almost had a heart attack.’’

One firefighter was treated for a minor shoulder injury.
