20th Street in Rittenhouse is a restaurant row of sorts. Lucky for us, Luna has joined the ranks of Pub & Kitchen, Twenty Manning, and 1-900-ICE-CREAM, adding an Italian BYOB to the corridor. The restaurant took over the former Casta Diva space, and after a small makeover, is intimate, charming, and buzzing with groups of friends, couples, and ‘80s pop hits. The menu is made up of shareable appetizers like calamari in a kalamata-tomato sauce, caesar salad, and antipasto with truffle-stuffed burrata, and satisfying mains like a 16 oz veal chop and branzino with Israeli couscous. But it’s the generously-portioned handmade pastas–from ribbons of pappardelle in a lamb bolognese to garganelli with sweet sausage in a saffron cream sauce–that have turned us from first-time diners into devoted regulars.
