I am definitely a fan -- have been for years! Love the HH at Kona Grill! Food is tasty and their sake bombers are wonderful!! They have a long list of happy hour food choices which is nice, not much for sushi aside from the standard, basic rolls, plus 3 "special rolls" which were certainly not three of their best. We also had the avocado egg rolls, cheeseburger sliders, calamari and flatbread buffalo chicken pizza -- all wonderful choices!!
The patio is great -- people watching and car watching doesn't get any better! The misters are an added plus in the summer heat. It does fill up and people do hover when your check arrives, but it's still worth it!!
FYI -- I have taken the kids before, they are only allowed on the patio, not in the bar area.
