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.

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!

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.

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.

Came here simply for drinks on one beautiful moonlit evening. There was a wonderful duo playing on the stage and the weather was perfect! The girls had Vodka drinks and I had the Hurricane, which was quite tasty.
