Mastro's Ocean Club anchors the Shops at Crystals at CityCenter — the multi-story Tree House architectural feature (glass-and-wood sculpture rising through the mall atrium) is the room's defining vibe. The Landry's-operated kitchen runs the Mastro's steakhouse-plus-seafood template: dry-aged prime cuts, towers of crab and lobster, the warm butter cake. The cooking is brand-level; the room is single-location-distinct. For the Crystals dining anchor where the architectural setting carries the editorial weight.
