I've been here multiple times and I've enjoyed every visit. I usually come for dinner, which you definitely need reservations for, but I've also just come for drinks and dessert and had a pleasant experience. The staff are accommodating and the food is consistently good.
The last time I was there, I had the mafalde ai funghi (mushroom pasta, $17.50) and absolutely loved it. I could have dunked my head in that truffle cream sauce, it was so good. I wanted to get another order of it to go, but I settled for the tiramisu ($6.50), which was a good call. But I'd recommend getting the Dolci Platter ($15.50) to share 3 of the desserts with friends so you can taste them all.
Come when it's warmer and enjoy the rooftop patio. Just watch out for the bees.
