Are you looking for a friendly local boozer serving real ale, a darts team, a pool table, or somewhere to hold a party or private function? Or are you just interested in the origin of the UK's pub names?
St George is the Patron Saint of England, and the Prince Regent in the Regency period was King George IV. Both are credible origins for pubs called The George. However in the case of the latter, The Royal George and The Prince Regent are also common pub names.
