I had a beautiful selection of oysters and the best halibut I've ever eaten. I really can't criticised the food but it doesn't come cheap. I would have given it a perfect score if it wasn't for the fact that the decor is quite austere...More

The largest area of the city, Downtown is rich with
historical and iconic sites in Boston. Stroll through
one of Boston’s most famous green spaces, the Boston
Public Gardens, check out and make way for duckling
statues, picnic under a beautiful tree overlooking the
pond, and walk over the iconic footbridge where,
during summer time, you will catch a swan boat toting
children and eager tourists through the pond. Have
