The march of the upscale restaurant chains continues, as Del Frisco’s Grille opens Friday at Walt Whitman Shops. The 21st outpost of the Texas-based eatery has taken over the old Legal Sea Foods space at the southern end of the mall.

The kitchen, helmed here by Seasons 52 veteran Seth Barton, puts out a menu of contemporary American classics given the of-the-moment over-the-top treatment. Starters (here “food to fight over” and priced from $8 to $17) include cheesesteak egg rolls with sweet and spicy chili sauce, roasted tomato flatbread with fresh mozzarella and Buffalo-style lollipop chicken wings with avocado ranch dressing. Among “two-fisted sandwiches” ($15 to $18) are a green chili cheeseburger with double patties and jalapeño Jack cheese and a lamb burger with sun-dried tomato, arugula and tzatziki sauce.

There are “greens big & small” such as kale and Brussels sprouts salad with almonds, dried cranberries, orange segments, Manchego and Creole mustard vinaigrette, and “knife and fork” mains ($25 to $31.50) from sesame-crusted ahi tuna over chilled Asian noodles and mushroom-shallot crusted steak with jalapeño-bacon mashed potatoes to roast chicken with “hand-mashed” potatoes and asparagus and Parmesan-crusted lemon sole with arugula-crab salad. You can also get a filet mignon, New York strip or rib-eye steak ($39 to $48)

There are “handcrafted cocktails,” five craft beers on tap (right now, Brooklyn Brewery Pilsner, Sam Adams Summer Ale, Greenport IPA, Blue Point Toasted Lager and Captain Lawrence Sun Block) and a wine list of more than 200 bottles, with 26 available by the glass. Happy hour is 4 to 6:30 p.m. weekdays and the bar menu includes wagyu beef corn dogs and pulled-pork nachos, $6 if consumed at the bar.

Del Frisco’s Grille is at 160 Walt Whitman Rd., Huntington Station, 631-423-0308,
