I ate at Libretto on King on Saturday night as a group of 16, for a friend's birthday. It was a $30 prix fixe menu (had been arranged beforehand) and worked out really well. All dishes were served family style, with multiple platters of each dish spread out along the table. We started with kale salad and gnocchi, then 4 different pizzas, and dessert platters. TONS of food, more than enough for everyone, amazing value. Food was great, service was good, bills were all separated properly, overall a great experience. I always enjoy the food at Libretto but now knowing they're good with groups, I'd definitely recommend it for a large party.
