Spontini, if you haven't been, is an institution in Milan not far from the 'Lima' metro stop. There is almost always a line out the door, and you will often here tourists complaining both about the line, and about the waitstaff who will actively hurry you out the door so others can be seated (can't have it both ways can you diners??)
The pizza, from what I have learnt since being in the forum is Sicillian in style? 2 choices on the menu, regular and I think anchovies. Pizza is served 'al trancio' by the slice for €5. Definate visit!
