The first time I went to Terroni I wondered what all the fuss was about. I didn't return for 5 years. Recently, I have lunched at Terroni twice. Both times, I was pleasantly surprised, but not bowled over. The calamari was pretty fantastic and the pizza's are very good indeed. The service was polite but not friendly, and the food came quick enough for a leisurely lunch, but not a good choice on a lunch break from work.
To me, Terroni is the devil you know, it's good, but not incredible and is a better choice than a lot of the other restaurants in the neighborhood. Would I go out of my way to visit Terroni? Not likely.
