Well, I'm too late to help for this Friday night...though I am curious where you decided to eat and how the gnocchi quest ended!
One of my favorite, reliable places to get take-out, delicious gnocchi is from Pasta Palazzo on Halsted, just south of Armitage and next to Gepperth's meat market. This gnocchi is stuffed with very light ricotta and would be delicious in any preparation, but we like to get it with the bolognese sauce (you can choose from among 4-5 sauces).
Pasta Palazzo is in no way a gourmet experience, but honestly, this gnocchi is like eating little fluffy pillows from heaven. Texture and taste (of the gnocchi specifically, though not of most other pasta dishes) rival many of the city's better Italian places. I hope you'll try it some time and let me know if you agree.
