On Sat., July 21, the family owners of the closed Jade Mountain restaurant on Second Ave. held an “Everything Must Go” sale, as little Nicholas Chan, above right, scampered about. Jade Mountain, which opened in 1931, closed in February of this year, five months after Reginald Chan, its 60-year-old owner, was fatally hit by a truck while making a delivery on a bicycle. The family has leased out the space for a tavern, which will open in November. A family member said that someone had wanted to buy the Jade Mountain sign and resurrect it for use at another restaurant located out of state.
