Oxford is great visit! (almost bought a bed and breakfast there many years ago). It has a totally different personality than STM. Be sure to stop in and see Cutts and Case boat builders while you're there. Good crab house there right on the Tred Avon, cant recall its name though? They have slips you can use while dining.
Is it the Masthead at Pier Street.?
We have eaten there a few times. It cures Donnas love for bashing crabs and cutting her fingers filling the cuts with Old Bay. Their crabcakes are for me..
