To the owner: train your waiters to take orders. Been here three times and every time takes waiters 10-15 min just to come and take orders. They see that menu is closed and we're just waiting. Looking back directly at three other servers as they just stand around talking.
You have to assign systems. Can't be all random. Assign table sections to each server, like every good restaurant does.
Either get competent servers or stop letting high school kids work at your place. Food is just average, but hard to come by good Korean let alone Asian food in Arizona.
