For more than 35 years, Boston’s has provided seafood and American fare in a casual and lively setting. Floor-to-ceiling windows overlook the beach, and indoor, patio and on the sand dining is available. Live music is often offered at “The Beach,” the first floor of the restaurant where shoes can get kicked off and toes can nestle into the sand. 50 Ocean is the more upscale seafood dining, and Boston’s itself is open for breakfast through dinner.
