Last year during Design Week, I came upon this cute "bistrot"-type restaurant. Big windows looked into a cozy interior, no tablecloths, casual, a simple, seasonal menu. Reviews looked good. But of course it was fully booked for the evening.
People can be surprised, but sometimes eating in Milan during Design Week can be a rather un-inspirational experience. You're walking from one place to another trying to see as many shows as possible, so you prioritize convenience and speed and pick up reheated pizza on the go. Or you decide to sit down, but the restaurants are completely packed.
