Umm... I was'nt ill as such just bit into a piece of chicken that can only be described as rotten!! Not nice!
Had a few from Didar and would struggle to criticise them but I do have a soft spot for the curry inn, they seem to make their cirrus both hot and flavoursome....
The best indian in HH by far is the curry inn down by the station. They are a good bunch in there and I'm sure the owner would cater for your condition! Give him a ring... Seriously worth it!
FYI avoid blue India like the plague!!!
