On Saturday night in East Hampton, reservations were scarce by six o’clock. At Nick & Toni’s, staff reported a wait for walk-ins stretching past an hour. The late-summer crowd is back in full force, with diners favoring outdoor patios and seafood-heavy menus.

At Sag Harbor’s Dock House, oyster prices have climbed to $3.50 apiece, reflecting both demand and ongoing supply challenges. Down the street, Lulu Kitchen & Bar’s wood-fired whole fish remains a popular order, with servers noting a steady stream of city regulars and weekend visitors.

In Montauk, the lunch line at The Lobster Roll—known to locals as "Lunch"—stretched to the parking lot by noon on Friday. Prices for the signature sandwich now hover at $34. Beachgoers in flip-flops mixed with families and retirees staking out shaded tables.

Restaurant owners say staffing remains tight. Many have limited hours on Mondays and Tuesdays, concentrating service for the Thursday-through-Sunday rush. "We’re seeing people book weeks in advance for prime times," said a manager at Calissa in Water Mill.

With August vacationers driving demand, the challenge for diners is less about finding a good meal than securing a seat. As the season peaks, the most popular Hamptons restaurants are operating at capacity, with late-night reservations and bar seating as the best bet for a last-minute meal.
