Ostra is one of the finest restaurants in Boston with outstanding food and attentive staff. Their seafood is among the best in the city. They also have excellent cocktails and a very nice wine list. Highly recommended!

My husband and I had a lovely dinner at Ostra. We had delicious grilled Spanish Octopus as a starter. For entrees, the sea bream and grilled red snapper are to die for! Excellent ambience, great service and wonderful presentation. Will come back again! 😊

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
