Take it from a local: Rupali on the Bigg Market does have a Curry Hell on the menu and years ago it was certified as The Hottest Curry in the World. I'm reasonably sure the 'World' should read 'UK', but it is true that 10 years ago, if you finished your Curry Hell, you used to get a SECOND curry for free. And yes, all the kitchen staff used to come out to have a look at the fool who ordered it!
