I didn't really get the hype of piano piano till I recently went to celebrate with some friends, and OH MY is it incredible. But so is the price tag ($$$$) so I would recommend this spot for special celebrations and intimate dinners rather than your average Italian restaurant outing (ahem - Terroni's).
We ended up opting for the family style sharing menu for four of us. Was about $55 dollars a person and they were really flexible with us changing a few things on the set menu. We swapped one of the pastas to try the bolognese and this was a hit amongst the group. The mushroom pasta was amazing (but I still think Cafe Nervosa's is better). The Cesar salad was nothing special, though the server was raving about it. Everything else hit the spot and was VERY fresh and well prepared, especially their chicken dish on a bed of savoury polenta. YUMMM.
One thing that sets this restaurant apart from others is their swanky decor and smashing good service. The waiter basically became our best friend and was kind enough to bring us a round of negroni drinks and chocolates as he knew we came to celebrate our friends' engagement.
One last tip. Make resos a week or two in advance to get a decent seat at a reasonable time.
Overall, 5 stars and would go here again. Thanks for an incredible night!
