Brunch Hog Island Oyster Company
If you are having Swan's oysters at the beginning of your trip - and Anchor & Hope with great seafood along the way - I don't think you need to hit up Hog Island for brunch unless you REALLY really want redundant oysters and not much else.
I'd consider other brunch/lunch places like Canteen or Dottie's True Blue Cafe. If it is one last, solid lunch you are looking for, there are more substantial meals that I think would be more memorable than Hog Island...
