This could be the list that never ends! A few personal favorites! Clarke Cooke House for sushi and oysters, Diegos for Mexican (brunch too), The Black Pearl for chowder, O'Briens for mudslides and pub food, drinks on Castle Hill's lawn!
Sightseeing/Activities
Second Beach (aka Sachuest Beach) in Middletown is the beach I most frequent! Tour the Newport Mansions! Cliff walk for ocean and mansion views! Shop along Thames or in Bowens Wharf. Newport Vineyards!
