He'd tell Mimsy to do a thorough reconnaissance of Muggle London and their shops and restaurants while staying invisible. She'd soon know where to get the kind of food he favoured.
He did not think it wise to keep Azriel from Andromeda when they were staying in his flat, but he did not comment. Stephen was right that it was his marriage and he'd deal with it as he wished.
