Customers walk in to an enthusiastic "HIIIIIIIIII" from the entire staff and are shown out in the same fashion. Sometimes the customers join in! This is a quirky sushi restaurant with really friendly owners/staff. My husband and I go in here a lot. If there is ever a problem (we go in often enough that this is bound to happen) the team at Happy Sushi is quick to fix any problems. It's not unusual to get a free miso soup, tea or sample maki when they have something new. In my opinion, some of their highlights include a sweet potato tempura and avocado maki and mango maki. There are plenty of options and they are all well priced.
