I have eaten here three or four times, and the workers have never been polite. They seem sad and resentful. This is despite whether or not I add a tip to the receipt. I keep coming back for the teriyaki bowls, but the Arizona bowl might give you indigestion. Prices are reasonable.
Also, for some reason they make you pick up your food at the register even though they have a huge empty counter. One of the workers keeps walking up to this empty counter and spitting behind it, so I guess I would prefer she stop doing that before serving the food there. But you literally have to walk in front of people that are ordering to get your food.
