North Miami Beach will have a new hot spot on Biscayne Boulevard as Chef Danny Serfer's Downtown seafood staple Mignonette will open a second location at the old Gourmet Diner owned by Rockwell Holding Group. The Gourmet Diner location is a 2,300 SF restaurant space at 13951 Biscayne Blvd. While the terms of the deal will remain private the list price was about $192K per year or about $16K per month triple net. Rockwell Holding Group is owned by Brett David who also owns the nearby Prestige Imports exotic car dealership. They purchased the old Gourmet Diner for $1.6 million in 2012. Serfer opened Mignonette two years ago and aims to preserve much of the historical charm of the old Gourmet Diner in his new restaurant.
