This must be one of the food which is specific to Amritsar - Kulcha. You know what is "naan" right ? Kulcha is like naan but stuffed with fillings like potato etc. Makes it super delicious and certainly one of my favourite authentic Amritsari dishes.
Never seen in Singapore though, or should I be walking about more in little India ?
There's a nice quaint little store near the city office called "Kulcha-Land" woo. If you think along the likes of "Disneyland" then I'm quite sure you are waaaaaaaaaay off, but yeah the Kulcha there is nonetheless nice, only about INR15 each (in sharp contrast to the INR25 at the hotel).
