See Pietro's commitment


The factory is a “huge kitchen”

The dressing is made with special “care” in the restaurant kitchen, and this “care” which has been there since the beginning, is passed on by the staff working in the dressing factory with every one of them carefully doing their part. Many of the manufacturing processes are still done by hand even today.
Delicious products are made not by machine but by hand. This will not change, regardless of how modern society becomes.


Many repeated steps in small quantity

There's nothing better than food made with time and effort carefully devoted to it. To ensure deliciousness that cannot be achieved in mass production, we use stockpots to prepare our dressing.

We do not mass produce using a gigantic tank. Placing more value on flavor than we do on efficiency,

we continue to follow the recipe to deliver a consistently delicious taste. 


The pursuit of delicious taste and health

We begin our production by first imagining the dining tables where Pietro products are being used.
The deliciousness is important, but we also hope to deliver joy to the people using our products
and wholesomeness for our health-conscious customers. We continue to strive to make such products.
