Gruppo di Amici benfits from lack of competition in Rogers Park; there just aren't a lot of good spots to dine there. In other parts of town, it wouldn't get much attention. The food is good, but rather overpriced - especially the daily specials. I dislike restaurants that have menu entrees substantially lower priced than the specials and that is exactly how it is set up at this restaurant. Menu entrees are around $14-$18, but the specials that are announced without price run $25+. Portions are large, so sharing is the way to go. The pizza is good.
There is a good, but inconsistent wine list - you get a wine that you like, but the next time you go there, they no longer have it. Service is pretty awful, frankly. Slow on a good day, unfriendly on a bad one. The atmosphere isn't as good as people here are saying either. They always have televisions on - ususally sports, so hardly a fine dining experience and the audio system is cheesy making the music either overpowering or inaudible depending on where you sit. Worse, they seem to have developed a snotty little clique at the bar that is unwelcoming to many.
I still go there occassionally because, as I said, there isn't a lot to choose from in Rogers Park.
