This seems to have changed hands to "Pizza Flor" but I can't find a location in Linate. This is conveniently located near the check in desks in departures.
You select the pizza and the amount you'd like, they weigh it, cook it briefly in the oven and serve. Airport prices - 4 euros for a soft drink, the carbonara pizza slices were almost 12 euros, but the service provided by the woman on the counter was phenomenal - she made my day immeasurably better. Thank you!
