We recently visited Hemenway's while on business in Providence. It was in a great location (heart of downtown) and had a wonderful ambiance. The food was excellent, just what we wanted... a real taste of the sea. We had oysters and scallops for appetizers and I ordered the mahi mahi for dinner. Filling and very good flavors - I would go back!
The only down side was the service. There were only six of us a the table, and yet everything took a LONG time from the kitchen. We were waiting 10-15min in between courses and ended up staying at the restaurant from 6-9:30pm waiting to receive/finish our meals. It could have been much quicker and the wait staff could have been more receptive. Other than that, no complaints on the food - wonderful!
