Touristy pub-style outfits run by companies cluster by the castle entrance, all of them serving fish and chips for around £10, but this creaky and potentially haunted wooden building from 1645 is the most interesting. It’s where Charles II is said to have stashed his mistress (“Rumored,” the waitress cautions) for easy access to his chambers via a tunnel, now sealed off. Family-run, it serves a gamut of British food from breakfast to cream tea to club sandwiches.
