Prime Steak Concepts — the group behind Steak 44, Ocean 44 and the recent buyer of Durant’s Steakhouse — has plans to open its newest concept in Scottsdale in the former Chart House seafood restaurant space on Camelback Lake.

Chart House opened in Scottsdale’s McCormick Ranch neighborhood in 1984 and is set to close at the end of this month. Prime Steak Concepts — which is run by brothers Michael and Jeffrey Mastro, Dennis Mastro and business partner Scott Troilo — acquired the 10,000-square-foot restaurant in July 2024 for $4.4 million, according to Maricopa County records.

The new restaurant will be personal for Mike and Jeff Mastro, who grew up right around the corner from Chart House.

“We’ve always loved this property,” Jeff Mastro told the Business Journal. “The opportunity came up to purchase it, so we grabbed it and then we’ve been trying to figure out what to do with it.”
