Went to Osso during restaurant week. Loved the atmosphere and had great service. The crab crostini, arancini, and pistachio semifreddo were awesome. The fig crostada was OK, but the lava cake was sub par. The crab and gnocchi entree was disappointing--it reminded me of bland tuna noodle casserole. A friend ordered the Osso bucco and raved about the flavor and tenderness of the meat.
