Had a wonderful dinner @ Il Luogo di Aimo e Nadia. I'd say it's more a ristorante than tratt/osteria.
Exquisitely prepared fare (had the ubiquitous risotto Milanese as part of the taster menu), swift and courteous service. Room was more casual than anything, but most tables were still somewhat dressed up.
Dessert was especially memborable: airy-perfectly-prepared chocolate souffle, enclosing a cherry gelato.
We stayed near the Duomo, and this restaurant was just a short cab ride out.

I have been living in Milan for years now and I don't agree with what NiKoLe has to say. For starters Bagutta (and not Baguda) is NOT a good restaurant. It's a tourist trap. The food in Milano is just "not okay". Maybe if you just go to BAGUTTA and Paper Moon it is but trust me, this city goes beyond Via Bagutta (which is where both restaurants are).
Here are a few restaurants for you:
Al Girarrosto da Cesarina
Alle Colline Pistoiese
Also if you want something very trendy but don't care much about the food, I would recommend dolce and gabbana gold. The design is unbelievable.
food in milan is just okay. My two best suggestions are Paper Moon and Baguda. They are both the best for lunch, although they do a decent dinner as well. If you go to Paper Moon, you must have their pizza! Its amazing!! Baguda has really good everything, pasta, fish, chicken, dessert, etc. you can't go wrong there. they are both fun places.
definitely make reservations in advance. they are very popular places even among the locals!!
