Milan on Sunday

We will be going to Milan in June and arriving on Sunday.Anyone Know of a good trattoria in the center opened on Sunday?

Not exactly a trattoria, but I’m pretty sure it’s open Sunday:

LUINI, very near the Galleria and Duomo in Milan.
http://www.luini.it/ Via Santa Radegonda, 16
20121 Milano, Italy
02 86461917

This tiny take out counter is an institution in Milan since 1948. People cue for at least 10-15 minutes before they can get their food. All sorts of people line up for a quick lunch, from Tourists to Milanese executives, students, construction workers, etc…What’s the secret of this place? I guess aside from a good location, they serve the best Panzerotto in town and fresh out of the oven. And what is Panzerotto? It’s a pocket sized pizza made with a donut type of dough, very light and a slight sweetish flavor (but not overly sweet). Inside, all sorts of ingredients can be placed: Tomato, Ham, Tuna, etc…but always with a base of cheese. I had the classic Ham and cheese (their best seller I was told).

I think this is open on Sunday. It’s a short walk from the center. It’s a great local restaurant in a nice neighborhood. There will not be a lot of tourists there.
