Seafood
Opened in 2016, H2O Seafood & Sushi in E Islip brings our signature seasonal seafood to the South Shore. The sea dictates what’s on the menu at H20, as, whenever possible, our Chef sources local fish and supports local farmers through creative takes in the kitchen. Grab a seat at the expansive gray marble bar while tasting startlingly fresh sushi or our modern American seafood classics. The sprawling menu features treats from the ocean, fresh Bluefin Tuna, Scottish Salmon and also satisfies land lovers with dishes like our flat iron steak with Sriracha butter or our pan roasted chicken with cornbread stuffing. Shareable desserts like the donuts with coffee pot du crème make indulging almost impossible to avoid. Cleverly designed with an upscale New England feel, you’ll feel like home in this warm and inviting space.

By far my favorite restaurant on the island. Outstanding service, food is always top notch, and our waiter even remembered us from a couple months back when we were here. Would highly recommend to any body looking for an overall amazing restaurant.

Food and Service was amazing. Ashley, our server, was very sweet & never missed a beat. Hopefully, you're as lucky as we were to have her when you dine there. Sandra stopped by our table and was very accommodating to our requests. The dining setup was odd but overall we had a great dining experience.

The service was great but the food was just average at best. We had lobster thermidor which had dried out lobster meat and a watery sauce, disappointed.

Food was good but, some tables are very small. Once our food started to come out the hostess realized that they needed to put the two of us at a bigger table, which there was plenty of. Not sure why they put us next to the kitchen, on that table, while there was so much more available in the restaurant and we made reservations on open table.

This place is expensive for what you get. My dish (chilean seabass) was lacking flavor - tomato caper sauce was good, but not flavorful and there was not enough of it. The potato pancake it sat on was really greasy and not tasty at all. I've had this before, possibly in Smithtown, and remember that I enjoyed it much more. For $39 I'd expect a more flavorful dish. Service was excellent. Ambiance is nice, but the temperature of the restaurant was way too cold.

Great Wine Wednesday Dinner; loved everything I was served! Started with a Romaine Wedge served with black beans, tomatoes, fresh corn, and onions in a delicious avocado Ranch dressing that should be on the regular menu if its not already. Second course was Pepper-seared Scallops served with a bacon and tomato relish. And finally the Seafood Linguini, consisting of shrimp, clams, lobster, asparagus and mushrooms in a lemon white wine sauce. Definitely one of the best linguini dishes I've ever had. As I mentioned to the crew, my compliments to the Chef and the entire kitchen team!

Service was top-notch as always! Warmly greeted and seated by one of the managers, Tracy. Jared the server remembered me from my previous visit and knew I liked extra water, extra napkins, and extra butter for my popovers. GM Angela made time on a busy evening to stop by and chat with me, which I always enjoy doing with her. Its that kind of personal attention that I receive from Angela, Tracy, and Jared that keeps me coming back regularly to H2O Islip. Oh, and the delicious food doesn't hurt :)

Thanks for reading!

My wife and I went for one of their wine dinner. The wine went well with the food.
The burrata/cheese course was delicious. The striped bass course was terrific also.
The tomato bisque with crabmeat was disappointing. Very little crab meat and basil.

I have eaten at H2O on several occasions and I have always enjoyed the restaurant. On this visit, however, the food was not up to par. My friend and I ordered the surf and turf for 2. It includes a shell steak and a 2 pound lobster. The restaurant ran out of 2 pound lobsters, and offered two 1 1/4 pound lobsters instead. That would have been acceptable had the lobsters not been so overcooked making the claws inedible and the meat throughout the rest of the lobster dry and tough. I would have said something but, the manager came over and made a big deal about substituting 2 lobsters and telling us we were getting a better deal because the 2 lobsters weighed more than the single 2 pounder. As an avid lobster eater, I can tell you that is not true. A larger lobster has more meat to shell ratio. In addition, when the lobster is so overcooked, a significant portion of the meat is lost and is not edible. The steak was good, as were the sides. We also enjoyed our mussels appetizer. Unfortunately, a seafood restaurant should be able to properly cook a lobster. I was disappointed but I will go back. Other visits have been much more successful and I will try the restaurant again.

One of my favorite places to dine. Started with the Shrimp and Lobster Won-Tons and they did not disappoint! First time having and it was a great appetizer.

I do wish they'd bring back the Monk Fish Fritters and the Mexican Street Corn, though.

My main course was the Sunday Surf & Turf Special which, for $24, is a STEAL! I've had it before but unfortunately I did not know they stopped putting the BBQ sauce on the shrimp so it was not as zesty as when I've had it before. However, I was told afterward to ask for the sauce next time, which I will. Oh, well! However, my steak was delicious and cooked perfectly!

Always happy to see Tracy from the management team. She came by multiple times to check on my dinner. Hostess Lindsay gave me a nice booth to sit in as I don't care for high-tops. Jared the server was friendly, knowledgeable about food in general and the menu in particular. He along with Erica the busser and Grant the food runner made sure I had plenty of water, extra butter, extra napkins (I'm a slob) and a dirty dish never sat for more than thirty seconds on my table. Compliments to everyone at H2O Islip for being so attentive.

I'm sorry my buddy GM Angela was off and I didn't get to say hi to her but I'm always happy when someone has a much-deserved day away from work!

This was the most disappointing meal we have had in a long time. It actually can't be called a meal because we never got our entrees. After 1.5 hours we were still waiting and the restaurant was full of excuses. Such a shame because we were looking forward to celebrating our anniversary there and love the other restaurants like Tellers and Prime.
