They are both pretty good...I love the cobb salad and salmon at HBD and the apps are good there too, but you certainly do pay a premium for the food. Kona is a good choice...the sticky wings are great and the tuna oscar was pretty darn good, too! I have heard you can order sushi from the Island sushi bar, which is even more reason to try it. If you can fit both, I would try both, but if you can do just one, Kona is certainly a little bit of a less expensive option.
