You do sound like a bit of food snob.<quoted text>
The UK with its large population drawn from the Indian subcontinent has many Indian restaurants that're mostly below par.
In London, the best Indian restaurants serving authentic Indian cuisine are Chutney Mary, Ameya and Veeraswamy's.
All 3 are owned and run by the classy and Cambridge-educated Camellia Panjabi who's on the board of executive directors (F&B) of the Taj Group of Hotels. She visits the Mumbai Taj often. In the Taj in Mumbai she has set up the exclusive and very classy Masala Kraft restaurant serving genuine Indian food.
To eat in these restaurants are real treats.
Very excellent food can be found at low end restaurants, street food for example sold by vendors. Diners etc. You should watch some of the shows on our Food Network.
Fancy restaurants are fine, but I enjoy a variety of dining experiences.
On our last night in London, we had planned to try offal. Are you familiar?
We got sick though and did not go out that night.
