No weapons in Canterbury! They will check at the gates. Just leave the blade at home. My son had a pair of scissors once in a belt pouch (persona of a cordwainer/shoemaker) and was refused entry-and he had been on cast the year before as that very person. Pickpocket set? How very interesting!
As far as pubs, there are a few neat ones around: Pirates Pub by the ship, and Codsweld Commons (I think?) near the center of Canterbury (it's a double decker!). Most of the others are walk ups. The Pig and Whistle has just a few stools, and the Drunken Starfish (by the mudshow) just doesn't feel period at all to me.
Post when you're coming, and we'll try to make you feel welcome!
