An outstanding experience, and a different one every time we come to H20. This time it was the "Aniversary Week" special menu. A three course dinner with wine pairing. My wife and I ordered different dishes and each one of the 6 choices was a masterpiece. The staff were amazing.

Wonderful experience. Server was attentive and on top of things! Everyone enjoyed their seafood and sushi items. I’m not a fish eater, but ordered the Filet Mignon Wellington. It was the best one I’ve ever had! Will be back. We even left a birthday card on the table with cash in it and they called us on the phone to come back and get it. Wonderful experience all around.

Another delicious meal at H2O.
I had your chicken for the first time. It was cooked perfectly and served beautifully.
However, the hostess was unable to find our reservation. Fortunately, I had the confirmation on my phone.

Outside setting nice.
Service needs improvement. With the server delivering the soup, I requested soup crackers that never came...Lady friend requested no ice water that came very late.
I took the Anniversary special with the wine pairing which was very good and a decent value.. My wife salad and her glass of wine were very pricey. My friends also mentioned the prices..
Nice weather with the fire pits and the full moon was special.

H2O Shines. We visited H2O's Smithtown location to take advantage of the special prix fixe anniversary menu that is on offer this week. Their Smithtown location offers attractive outside seating, which was important to us and our guests during the recent resurgence here of COVID. Our branzino and swordfish entrees were outstanding, and the three-course prix fixe dinner was a steal at $35. The menu even included a NY strip option for our landlubber friend. So, how could we lose?

We ordered 2 Bloody Mary’s. The waitress came back and said there wasn’t any tomato juice! She claimed that they usually don’t make bloody Mary’s except for parties. This wasn’t our first rodeo at H20. I always get a Bloody Mary. We are frequent BRG customers at all their restaurants and I have never heard, we don’t have any tomato juice. Oh well
There were no paper towels in the men’s room or hand dryer. Ok I’ll use my shirt.
The waitress was less than pleasant.
The food was excellent!

My husband, who is an alcoholic in recovery/sober for the last 12 years, ordered a tonic water with lime. The waitress brought him a vodka tonic. We told her immediately, and she took it away and brought him his tonic water. When the waitress brought us our bill, she hadn’t taken the drink off the bill.

The food was otherwise good.

Our server, Janine, was very patient as I tried to find the right beer. She guided me in the right direction and I now know that I like IPAs and not regular Pale Ales. My wife and I do not go out very often and picking the right drink on nights like this is very important for our experience. She was also very helpful with explaining the dishes and making us feel comfortable and excited about our choices. Bottom line is that she didn't just serve us, she took care of us. That along with great food makes a happy customer.

Having frequented H2O for many years, I was extremely disappointed in the entire experience. The dining area was not being kept up, the service was awful despite many employees walking around and the food quality was poor. We ordered a dozen clams and a dozen oysters and only received 6 of each. Good thing as they were on the warm side and didn’t taste fresh. Didn’t want the rest (and no hot sauce available?). We had 2 sushi rolls that fell apart as they too were warm. For a place where seafood is the main feature, that’s not a good sign. Our main meals were sad looking and bland. When I asked for a towel to dry off the table in between courses, the waiter brought one over and dropped it on the table for is to use instead of doing the right thing and wiping it up for the customer. It was a complete disappointment. I have been here at least 10-15 times in the past 2 years and after this experience there will not be any more trips here. For the prices they charge, they should be providing a much higher quality experience (like they used to).

Wine dinner; amazing value, but not up to previous experiences. We are frequent guests and like our servers, Michael and Nick. Taylor was busy and not at their level. The buratta was okay and, while the tuna was good, the portion was small. Really good herb pasta bed. Hahn Pinot Noir was nice….the Bedell Rose was uninspired. Still, we love H2O

First time visit last night. Will definitely not be our last! Love this place! Ordered popovers and the tuna poke nachos - both delicious! I ordered flounder for entree and my husband ordered the shrimp and lobster fra diavlo. Again, well-prepared, fresh and delicious. Our server Michael was wonderful - friendly, attentive and helped choose menu items to order. Great experience!

Although the food was good, as usual, we were a bit disappointed by our anniversary dinner at H2O. We dine there a few times a year, mostly on special occasions. Usually we have a very nice time, being treated very well. However this last visit didn’t feel as special.

Our server was pleasant, but although she wore a mask, it was below her nose the entire evening, even when she was at our table speaking with us.

The menu seemed a bit less inspired and the food a bit less extraordinary than we remember.

Where else would we go on our 48th wedding anniversary but to our favorite Friday night date venue? As usual the food and drinks were outstanding (thank you Brittany!) and we have never had a bad server there. Every server is friendly and attentive!

The food was great as usual, but I was disappointed to see they now charge $2/popover when they used to be given in a basket for free with every meal. I also noticed the prices went up but the meal sizes were a bit smaller. Service wasn’t as good as normal, but I think they must have been short handed.

Wednesday wine dinners are always a favorite of ours. Wednesday August 25 was outstanding. The appetizer of baked clams was the best we have ever had. The hanger steak with horseradish was wonderful. Thinking about the grilled peach dessert still makes my mouth water. The wine pairing was perfect. Thanks for a great meal!
