They have a great menu with quite a few options. Someone next to us ordered the avocado burger and it had half an avocado on top of the hamburger. My burger was $7.95 and Mark's sandwich was $9.95. A large order of fries was $4.00. We tried their lemonade. But I prefer a sweeter one and wouldn't order that again.
Conclusion: We would definately go to Kua Aina again.
Sorry about the pictures. We were halfway through the meal before we thought about snapping a few pics.
