I second the shrimp trucks on the North Shore. They are typically a very good value and you get a ton of food. Also in the North Shore in Haleiwa (not sure if I spelled that right) is Matsumoto's where you can get shaved ice.
For breakfast, I would recommend Boot's and Kimo's in Kailua. It was recommended to us by a bellman and Aulani and they had amazing macadamia nut pancakes. Go early though if you can because there is typically a wait.
Just Tacos in Kapolei across from Aulani was reasonable (it's not just tacos) as well as Monkey Pod Kitchen. From what I remember, Monkey Pod has some great happy hour specials like half of pizzas and others things so you may want to check if they still offer that.
