Traditional steak houses are where deals get done. There are also those raucous family restaurants. Then there’s Catch Steak, which comes with a soupcon of sex appeal, already attracting a glamorous crowd to see and be seen. The food is at the center but the high-energy crowd makes the place hum. This is a destination restaurant—dressy and at the same time, high-spirited. At the entrance to the 10,000-square-foot space is a glitzy bar with couples nuzzling and singles mingling.
