Completely impressed by this restaurant! The food, service, atmosphere, and location was perfect! I started off with an order of calamari- delicious, and ate an order of gnocchi which was superb. After, I had the calde calde. It was almost like a doughboy, but even better! The hostess, waiter, and bartender were all very accommodating and polite. I sat in the bar, which is always full due to the spectacular experience Costantino's brings people. 5 stars and best in Rhode Island!
