Do you have to pay per person and eat as much as you want or do you pay for how much you order/eat

Either or. You can get your own dish or get a "buffet" option for both. I dont remember if there is a limit in how many people have to be present to order "buffet" style.

You can order a plate or all you can eat. Great place

So Busy

Its per person, and each person has to pay for the same type of all you can eat option.

You pay once and eat all you want. Everyone has to pay if they want to eat
