My friend and I recently ate at the X&O Trattoria in Quincy Center and were pleasantly suprised by the quality and the ambiance. The food, though not quite as good as that found in the North End, was respectable. I had the Capellini Pomodoro, my friend the Chicken Parmesean. Both were quite good.
Wine list was not very good--- I expected more of a range of prices and qualities.
I also made the mistake of ordering the Bruschetta--- possibly the worst I've had anywhere. The portion was too big even for a group of people, which was a big waste since none of us liked it.
The service here is very friendly and professional--- especially given the riffraff that staffs the neighboring south shore restaurants. It's hard to find good help, but X&O seems to have found it :)
Prices are reasonable--- hardly an entree tops $20. Decor is very nice as well.
