Pizza in rome?

i just returned from a great trip to rome, but one thing has haunted me since i've returned. on our last day, my sister and i went with our parents to a little pizza parlor somewhere near the north american college of bishops. it was on the corner of via del corso and another street (NACB is on Via Dell' Umilta', if that helps). the corner that this place was on seemed to be under construction? it had an awning over it that gave that impression. it was down the street from galleria alberto sordi, the mini-shopping mall with zara and jam.
the food was not very good at this place, they basically just heated up pasta that had been sitting out (we didn't know at the time...), and it was very small. my sister and i befriended the waiter, who was probably close to our own ages. he told us to come back again before we left and he would get us decent food, but then we had to go home
does anyone know the name of this place? if they have a website? anything that i'm talking about???
Additional Details
EDIT: obviously, google was the first place i checked, followed by all of my old travel books. since i don't know the exact location or even the name of the place (we just saw it, were hungry, and went in), it's really hard to find anything
