Service bad, but good option for relatively cheap greasy burgers. For veggie-there is a veggie burger option as well as spicy toppings.
The black bean burger is scrumptious. But overall the decor is kinda tacky and old. Definitely a place for quick touristy food (not high end delicacy).
If you only have room for dessert this is the place. Sure it's a chain around the US but it's selection of cheesecake by the slice is mind blowing. Right next to the Waikiki Apple Store.
