Oh man, the never ending pasta bowl. Back in college my friends and I used to do a yearly contest to see who could eat the most. Everything had a point value, like a sausage was 2, a meatball was 1, etc. In my prime I managed to down the initial (large) bowl, 9 (smaller) refill bowls, all of which had 1 meatball or sausage, and a plate of 9 meatballs. That was the most disgustingly full I've ever been, and I remember how finishing those last few bites felt like the fork weighed 3 tons. Those were the good ol' days.
In terms of Italian, I'm partial to the family style places such as Carmine's and Maggiano's.
