AmEx is promoting a backend Offers discount program with various restaurants (groups, chains, and independents) via a microsite - https://amexdining.com/

Are there restaurants on this site that those who live or visit the UK would recommend (probably focused on the region surrounding London)? I am sure there are a number of not worth it or overpriced options or tourist traps, but trying to see if there are a few that might be worth considering this Fall (program currently scheduled to end in mid-November).

This also means it is possible to stack with other discounts (non third-party offers) since this offer is done as a statement credit...
