Although not quite the same, Shanghai cuisine draws from both Jiangsu and Zhejiang (you can read more in the book I lent you), and there a few Shanghai restos in London (proper ones not the ones with Shanghai in their name).
RE your comment '......the direct-controlled municipality of Chóngqìng (重慶) is adjacent to Sichuan province, and used to be part of it, and so there are multiple similarities between the cuisines of the two areas.'
IMHO, there are no two areas, there is one: Sichuan. Don't let the false distinctions created by the Chinese Communist Party interfere with food and culture. Just because a cartographer drew a line on a map 14 years ago doesn't make Chongqing any less a part of Sichuan.
