The most recent myth about Dover is that it is 'home' to large numbers of asylum seekers housed in its legions of B&B's. This is no longer true - if it ever was - partly because the tensions arising from such reporting meant that a policy of 'dispersal' is now followed. There is evidence though of relatively recent arrivals (from the 1990's) who have now settled in Dover. Polish and Hungarian restaurants are dotted around the town.
UPDATE: The building described above as the County Hotel is scheduled for demolition as part of a new development for an Asda supermarket. It's not actually the County Hotel either, which is next door, although the two appear to be physically connected. It is an empty office block which sits on the site of the former Grand Hotel, a vast Victorian palace of a building destroyed by bombing in the second world war.
