Katsusanderia is a showcase located between Risorgimento area and Piazza Cinque Giornate area, specifically at Sidewalk Kitchens (a "street" that unites different food and wine realities to be consumed in a street food version).
Originally Katsusanderia was born inside Bentoteca as a delivery project by chef Yoji Tokuyoshi, but today it has a space of his own.
The menu is essential: the katsusando (famous Japanese sandwich with pork cutlet, here called classic katsusando and enriched with herringbone, spinach mayonnaise and tonkatsu sauce) is obviously the star, but there are also egg variants (tamago sando, with chives, soft egg and mayonnaise) and with yakitori chicken (katsusando yakitori chicken, lightened and made crunchy with carrots and zucchini).
The proposal includes chirashi (with salmon or vegetarian) and some side dishes such as potato salad and tsukemono.
A nice gimmick "off the menu"? The "What katsu do you want?" T-shirt to buy at checkout!
How do you eat at Katsusanderia, then? Very good. The sandwiches are generous and fragrant, the filling is tasty and balanced, the shokupan bread is soft and delicate - the latter is the work of the Japanese baker Nishikata Ken, whose productions can be purchased at Terroir (still located in the same neighbourhood) or tasted at benthoteca.
The place is literally that of the street, since it is precisely street food: sheltered seating areas have been set up along the sidewalk with gazebos and heaters, in order to protect customers. In the winter season perhaps eating outdoors especially in the evening is not ideal, but if you pass by for lunch I'm sure you will still be fine. In this regard, I recommend eating on site: there is also a delivery service, but in my opinion, eating sandwiches immediately is certainly better.
All this is combined with a kind, smiling and prepared staff, which will make the experience even more enjoyable.
