Lucca is a fine Italian dining experience. Having lived in Italy for nearly 2 years of my life, I can say this place is the most authentic in Pittsburgh. Now if you want a menu with typical Americanized-Italian (Stromboli, calzone, Alfredo, etc), then Lucca will shock you. Yes they have a delicious steak on the menu. And yes, steak is very Italian (central Italy).
Fantastic appetizers (stracciatella cheese with olive tapenade was incredible), insalate mista was spot on, and for an entre I had swordfish with capers a lemon sauce, side of red sauce bolognese pasta. wow. So good.
Truly a 5-Star establishment.
