There's a very fine indian shop located at Bukit Gombak but I can't remember the shop name..it's situated directly at the Bukit Gombak Central (u can see the Central once u get off at Bukit Gombak MRT Station).
This indian shop is situated at the corner of the same lane as the chicken rice coffee shop(facing the community centre)..it's got a wide variety of any spices u need.
you name it,they have it.
Hope tis might be of help to you..
