    For Birthdays, I would get a 25 gift card for a return visit. I guess that’s been discontinued. Other than that, note, everything was great. I’ll be back for many early dinners.

    We have been to H20 many times and loved it. That is why I decided to take my husband there for his birthday. We each ordered a popover which we normally love. They tasted stale, had Burnt spots on the outside & were cold on the inside. We each ordered an appetizer, salad and an entree. We waited 45 minutes before any food was served and they brought the appetizer & salad at the same time. The food was good but my soup was not hot. Then we waited another 40 minutes for our entrees which were very good. The waiter said he would take the cost of the popovers off the bill but he did not. We didn’t want to bring it to his attention because it would have taken too long. The service was so slow which was not typical of our past visits. I don’t usually complain but last night was not one of our better dining experiences.

    Too too loud. I requested a table far away from the bar so the noise is reduced a little. Instead we were close to the bar. Our friends were already seated so I didn’t say anything.

    Upon arrival there was no available parking lot spaces and nothing located nearby. Once we were promptly seated inside, our server Mike was cordial, efficient and accommodating. Once he took our food orders and delivered them accordingly. Food presentation was excellent, dish serving size ample and tasty. Great value and experience. Will return again. I recommend Bohlen group. Great job.

    Enjoyed the Anniversary Week offerings with Wine Pairings. I had the skirt steak with chimmichurri and my husband had the surf & turf which cost additional but he said it was worth every penny. Sat outside and enjoyed the fall evening. Always a winner!

Not a long wait time from the bar to your table . Waiting staff is incredible !! The sushi was on a different level compared to any other , the beef Wellington was outstanding ! I highly recommend this place being a restaurateur establishing many different restaurants, (G$)

    Someone was smoking weed outside and smell was overpowering. Salmon appetizer was great, flounder mushy - would have preferred twice as much spinach and half as much flounder. Root beer float was not good at all. A simple dish of ice cream would have been better

    We ate outside for the first time. Won't do that again. It looks lovely, however the noise from Jericho Tpke and view are too loud and unappealing. Stick with indoor dining, it's much nicer. The Bronzino special was very good. The Rainbow Roll was okay. The service was very good.
