Acero Trattoria is a very small place that opened less than two months ago in the Porta Romana area. It is a sort of Japanese bistro run by a very kind and silent Chinese couple.
The place is nice, a triumph of colors, flags and posters of the master Hayao Miyazaki and while you are having dinner you can listen to the musical themes of his most famous films.
The seats are not more than six and for this reason Acero Trattoria is well suited to the takeaway formula or at most for a light and fast lunch break. The service is equally quick but still kind and the dishes are served in the take away containers.
The menu is essential: dumplings (you will find the classic gyoza but also the shao mai and the Chinese dumplings - this is the only non-Japanese parenthesis that you will find on menu), donburi (I recommend the gyudon), a couple of small salads, different proposals of chirashi, nigiri and gunkan mainly of salmon, tuna, sea bass and octopus.
All dishes are very simple and almost all are freshly prepared, tasty but with room for improvement - sushi rice, for example, was really too sweet in my opinion, while the dumplings I ordered were bought, not made by them.
The bill is really negligible, so if you are in the area and want to have a quick unpretentious meal this place is the right place for you. However, there's also the delivery formula.
Trattoria Acero is a place that has yet to break in and you can see it in every aspect. My advice for the property is to take better care of the dishes and try to communicate more with the customers.
