If you are staying at the Hilton and want a very casual meal, this is probably the easiest place to go. Meals are not cheap but food quality is ok for Mexican. Amount of food is adequate. Just don't expect a large portion. We seem to go there multiple times each trip to Waikoloa as it is just easy and casual which on some nights that is all you want.
Burrito is good. Taco salad is very good. Tacos and quesadilla are good.
