I'm a big fan of Kona from wayyy back. The only time I come is during happy hour!
The deals are decent and the drinks are worth the price. You can get a nice Margarita for $4. They changed a few of the recipes which turned out nice. The new pizzas are pretty decent and are more of a thin crust which I personally prefer. Its best to eat on the patio. Even on a hot day they have nice misters and fans that really keep you cool. The only problem is the outside of the patio has little bushes that attract bee's. So if you're sitting next to gates on the outside of the patio, beware.
I'm not a huge sushi lover so if I do have a hankering for it, I personally prefer to go somewhere that is known for having really good sushi, this place isn't but the other stuff they do have is pretty legit. Their clam chowder is some of the best i've eaten and almost always partake.
