Surf and turf has taken on a new definition in the last decade or so, moving from the old gray filet mignon and a broiled lobster tail combo to outstanding beef and sushi. Here are three steakhouses where the first-class seafood rivals the red meat.

Last year’s big addition to Northern Boulevard’s steakhouse row, Union Prime Steak & Sushi succeeded Burton & Doyle and transformed the place. Recommended: crabcakes, colossal crab meat cocktail, grilled octopus, Dover sole meunière, sushi rolls, strip steak, filet mignon, porterhouse steak.

 

TELLERS: AN AMERICAN CHOPHOUSE, 605 Main St., Islip; 631-277-7070, tellerschophouse.com
