On this weekend before the Fourth of July, celebrate the hamburger. Here are some casual spots where you’ll find the flavor of nostalgia served with casual style and some flair.

All American Hamburger Drive-In in Massapequa has been a roadside destination since 1963. Ultracasual, often crowded, and fast. Bring the whole softball team. Dive into the double cheeseburger or the quarter-pounder with cheese. The all-beef franks have their advocates, too. A thick shake is the apropos beverage. Some outdoor seating. No credit or debit cards.

American Roadside Burgers in Smithtown is a link in the national chain. You’ll be lured by the bacon cheeseburger; the Route 66 with barbecue sauce; the “hot mess” with applewood-smoked bacon, pepper jack cheese, and jalapeños. Chicken sandwiches and hot dogs are the competition. Tables inside.
