Montauk hotspot Maison Close burns to the ground day before slated opening

A chic new Montauk restaurant-nightclub burned to the ground a day before its planned Memorial Day weekend opening, and investigators are probing what sparked the fire, authorities said Friday.

Maison Close Montauk — a French-inspired hotspot with a star-studded flagship venue in Soho —  was destroyed by a blaze Thursday night, a spokesman for the venue told The Post.

“We are sorry to announce that last night a fire claimed Maison Close Montauk last night,” the rep said Friday.
