Thank you all for making the 2025 season at Seaside Grill memorable! We’ll see in May of 2026. Sipping margaritas by a on a sunny day right on the water…what could be better during the summer on Long Island? The Seaside Grill, located adjacent to the Hyatt Place East End & Resort Marina, is the newest seasonal hot spot to hit Long Island’s East End. With views of the lush scenery of the Peconic River, along with the boats dotting the shore at Treasure Cove Resort Marina, patrons can enjoy brunch, lunch or dinner while sipping a cool drink either poolside or at our waterfront dining area.

You can’t beat waterfront dining in the summer! Beautiful view at the marina on the Peconic River. Cocktails were very good. Service was great. Stick with the bar type of food the menu The chicken sandwich was delicious. Their attempt at seared tuna was not so good. Dry and chewy, served with unseasoned rice.
None the less we will probably return.

What a cute little spot on the Marina in Riverhead behind Hyatt Place and the LI Aquarium. We had the Coconut Mojito and Patron Margarita and its served nice and big in a cup, worth the drink price unlike other places. Burger and Lobster roll too. Come hang by the boats and have a nice laid back fun day. Tell ’em Barsnobs sent ya!

Great water views service, waitress daytime experience was great!Returned for last call paid for upgrade tequila on our margarita and bartender tried to pass off house tequila.
We called her out and she got an attitude thrusting the drink in the sink and remade lousy sour undrinkable last call. The food was great lobster and steak tacos. Hummus was hard and not edible. Worth another try obviously the bartender was having a bad night. The humus was not a choice for this seaside grill. Stick to obvious menu bar food.

My husband’s chicken came out raw but they replaced it with a burger & comped both meals. Overall the food was tasty with decent prices. The waitress was very nice 🙂

White wine sangria tastes like a pineapple drink. The lobster was a little rubbery for $35. Go with the simple stuff and you’ll enjoy the view better.

I had a pretty awful experience. The food was okay, charcuterie platter was a 25 dollar rip off and came with our neals. Cheese was in tiny cubes, old hard and sweating, no bread or crackers. My wings were okay, margaritas was good. The waitress disappeared after our order and the server wasn’t much more available. There were only two tables, no one came to check on us or ask if we wanted anything else. Then we were overcharged after hunting someone down. I was very disappointed, we went to Jerry’s for Irish coffees afterwards which saved the evening.

8 bucks, for over cooked dry chicken, I don’t even know why they put a spoonful of salad on it. Certainly ain’t pretty.
Staff was friendly and attentive, location is great.
Margaritas were good!

Atmosphere was great by the harbor. Staff was friendly and attentive. Drinks and food were great. Had the quesadilla and shrimp tacos. Had the campechama for an appetizer, the crab was delicious!

The event was a nice addition to Mother’s Day. The waitress was the best. The drink was tropical and tasty. And the wings were the bomb! The music was top notch. Thank you Michael for the beautiful music. The atmosphere was great by the water with just the right amount of lighting.
