Before anything else - this is my favourite local Indian Restaurant. Been eating there for a few years now and will continue to do so.
Secondly, 'several ambulances'? People 'writhing on the floor, fainting and vomiting'? Here's what actually happened:
Restaurant holds a curry-eating competition. Top of the list in the later rounds is the 'Kismot Killer', a curry that recently replaced a naga-based one, as too many people were finishing it easily. Anyway, if you order a killer, the restaurant staff will do everything in their power to put you off - there's warnings all over the place and you have to sign a disclaimer before eating it. If you *really* insist on eating the damn thing, you can't say you weren't warned. But anyway. So two people get to the later stages (one American, FWIW) and one of them has the bright idea of vomiting immediately after eating so as to avoid the after-effects. The other continues eating *despite being in pain and feeling faint*. I mean, seriously? So despite having the red cross present (it was a charity event), they got an ambulance to take these two to hospital for safety. The hospital gave them strong anti-indigestion medication and kicked them out.
Short version - idiots did idiotic things, complained that they shouldn't have to have any personal responsibility when the inevitable happened.
