Janani dear,
Main branch of Karachi bakery is at Mozzamjahi Market and also at Banjara Hills but all local super markets will also sell them.
You can find them in stores of Railway station or MGBS, i buy them sometimes when i don't have time to buy them before

and Fruit biscuits are very yummy when compared to almond or kajju!
You want Kalanjali printed material or kalamkari..? Yeah as Latha mentioned you can find them at Narsings in Ameerpet (the one beside RS.Brothers) they are so many branches of this particualar shop in near by galli's..
