You've read the other reviews, so I'll try to tell you something different about Filippo's place. Firstly, look at the map, turn left out the front door and keep walking and you'll get to the famous canal. Go on a summer evening and it will be pumping. Have fun!
Secondly, down below there is a pizza chain selling Milan style pizza, very different and worth a try.
Thirdly, turn right out the door and you'll get to the outlet of a famous chain of pastry/coffee shops. 1 euro for an espresso and 1 euro for a delicate pastry, artful creations.
Thirdly, unless you are there in August, go to Viale Coni Zugna near Via Savona to the Vermouth bar. What a classy Milanese experience.
...and while you're at it, the samples and 2nds from Milan's high end fashion industry are right on your doorstep at the Saturday morning market.
