We so enjoyed the Wednesday wine dinner this week. The food and wines were perfectly paired. Loved it! Steak, mushroom soup were wonderful and the carrot cake was perfect! Thanks for a great meal!

Went for the Wednesday night Wine pairing and price fix menu special. The Price fix was $40.00 for three courses and an additional $10.00 for the wine pairing which included a pairing for each course. Mushroom soup was amazing and I was expecting a little taste of wine but was pleasantly surprised when we received a full glass with each course. Skirt steak was the main course and it too was very good. Meat was tender and the gravy was delicious. Finally the desert was carrot cake, Just when I thought it couldn't get any better, it did. Cake was to die for. the ambiance was enjoyable and the service excellent. We are never disappointed when we eat at H2O in Smithtown.

fair service, over cooked food, noise level where you had to shout to be herd across the table. Overpriced for the quality.

Amazing experience! The waitress was very knowledgeable and she tried to accommodate me as much as possible with my celiacs disease. Lots of gluten free options ! It is pricey but I find the experience worth it.

Very nicely decorated restaurant with an excellent atmosphere as well. The restaurant was busy so the noise level was a little high but certainly not that bad. Both our meals were well prepared and excellent.

Had another wonderful dinner at H2O. Sat at the bar and had a wonderful bartender named Jessica. We had a few of the happy hour appetizers, like California roll, wedge salad, and shrimp. Then shared the Beef Wellington for dinner. Fabulous! Two great martinis to start, and two nice glasses of wine, all delicious! Will be back soon.

Food and service was very good. Drinks are nice they pour more than a 1 oz. We had to send the tuna back for a little more cooking as it came out on the raw side would have been fine for sushi fans. Over all pricey buy good.

We have always enjoyed our dining experiences at H2O, and last evening was exceptionally excellent. My husband and I celebrated our wedding anniversary by dining at H2O. The staff made us feel so welcome, the food was spot on, and the ambiance was perfect. We look forward to going back soon.

Honestly, I was quite disappointed. Husband and I took two other couples out to dinner to thank them for working very hard to help us out. Everything started off very nicely, but the restaurant did not have what we wanted to order. So only one person at a table was able to get it. The food was not as I had remembered from the other times I have been at this restaurant, which is a little embarrassing, these are people who really understand food and restaurants. Luckily enough the conversation and company we’re good and helped the night goes in there than it would have otherwise. As I said I am very disappointed in my experience, and therefore it will not be soon that I consider going back there again

Everything was outstanding with one exception - we felt "strong-armed" a bit by the manager(I suppose - woman in a white jacket). I guess we were so relaxed and enjoying ourselves, we didn't move fast enough to leave our seat. She reminded us with a "tone" that was unfriendly! Nevertheless, I'm sure we will return because H20 has always been a fave. That unfriendly tone was the first time we ever experienced that and we have frequented H20 many times. Our waitress was super!

One of the best meals ever. Swordfish was perfectly prepared and wedge salad delicious. We did find the main dining room noisy and difficult to have table conversation but the seafood can’t be beat.

I was going to H2O this past Wednesday with the intention of using up one of my $25 gift cards. However their Anniversary Week menu looked so inviting, I had to order it. And it was so good, I went back last night for another meal. Tomorrow, Oct 3, is the last night this menu is available. They may already be completely booked this weekend, but if they aren't, GO! I strongly suggest the lobster bisque and burrata salad because they are both amazing and not on the regular menu like the other app choices are. The branzino a la plancha is a regular menu item but I had never had it before. It, too, was great and I I had it twice this week. For dessert I suggest the red velvet cake with vanilla bean ice cream as it, too, was special to this week. I enjoy eating out side on their patio. It wasn't too cold, especially near the heaters. Both servers this week, Michael and Eric, and the servers assistants were all very attentive. Associate manager Dan very nice to chat with. And always great to see assistant manager Tracy, who is one of the best Bohlsen Restaurant Group people! Thank you for reading!

One of our favorite spots. Consistently good food and atmosphere. Our first time trying the shrimp tempura and words can’t describe this dish! It should be illegal …that’s how good it is!
