Been here twice and liked the burgers both times. There is a teriyaki-like flavor in the meat but it doesn't overwhelmed the toppings and sauces that comes with it.
The only drawback is the speed of the food. The servers were generally prompt in taking the order, but it took the food a while to come out. One time the restaurant was busy and second time not.
I would come back but I would need to plan for more time to eat and not come starving so I don't get irritated by the wait.
