It’s important to order right away when you sit down so things start coming to the table.
Order base soups, water and drinks on iPad first. Submit.
Then order meats, vegetables, noodles. Submit.
Then order cold side dishes, more food, etc.
Basically order in waves, getting more of what you like. You don’t want to take forever ordering and waiting for everything because of the time limit, and you don’t want to over-order.
The sauce bar usually has a line, so go right away after ordering the base.
