Big fan of Mario. Went to his NYC restaurant before he was famous. Otto has a nice, lively outdoor area but we opted for indoors for a more intimate evening. The decor was nice but a little too formal for a bistro. The Margherita pizza was evcellent, better than what we had in Rome. The gemelli pasta with brocolli rabe and housemade sausage was really flavorful but the pasta itself was too al dente for us. We thought they should have offered to shave some fresh parmesan on the pasta dish but they didn't. The appetizer fritti arancine (fried rissoto) was excellent; the fritti di Prosciutto was not as good. Pistachio and dark chocolate malt gelato was as good as it gets; really smooth, rich and flavorful. We found the wine by the glass and by the ounce way too pricey; a 4 ounce glass of their middle of the road white and red cost as much as our entres.
