Coming into H2O, I honestly didn't have the greatest expectations. The interior was quite nice. Although, the menu felt empty. The food was pretty good and the nigiri had a nice fish to rice ratio. Unagi was limited, so it wasn't offered as nigiri which bummed me out a bit.
The reason why I'm giving H2O 2 stars is because of the service. Our service was pretty good in the beginning, though he would forget stuff here and there. But our server went on break and told us we would have a different server while he was gone. No one showed up to our table, and even when we would ask someone working, they would just tell us they'll go and grab our waiter, who seemed to be nonexistent? We sat there for an hour with barely any help, so my friends and I just wanted to pay and leave. It's pretty good and since it is new, I hope their service improves.
