Trendy little spot good for happy hour specials and people watching. This is one of my favorite spots in Summerlin for day drinking, and yes, I have more than one. (Don't look at me like that!)
The sushi rolls are unamazing, but definitely edible and there are other good noshing options on the menu, such as kalamari, potstickers, etc. The margaritas are stiff, beers are the standard $3-4 on special.
The real draw of this place is the people watching, especially on a Friday evening when its packed. Kona is the preferred watering hole for the hot cougars of Summerlin, and the men that love them.
I fit into neither of these categories, but I enjoy this place a lot, and I'll probably be back.
