When you order your Udon, you select the bowl you want to put it in. If you're hungry, you pick the larger bowl and put 2 ladles of Udon in it. There are bowls for 3 ladles but that is rarely used. One ladle of Udon will satisfy most hungry Udon eaters. After you select your Udon, you select the side dishes to compliment your Udon. The side dishes can be placed directly inside the bowl of Udon, or eaten on the side.
The real treat of eating Udon is that there is no wrong way of enjoying this!
