5 /5 M P: I discovered this store called Sambal located in Colindale and went to shop .
The store offers all kind of Sri Lankan food options including take away options and there is an App to download called Sambal.
I purchased Sri Lankan souce for chicken curry and bought Lamb Roti, it was very tasty, the lady warmed it up for me.
I saw ready food options with rice, chicken vegetarian foods, snacks like samosa and roti, Hoppers, variation of curries. There is also a fridge section to buy packaged foods for after.
The store sells deserts and cakes: carrot cake, chocolate cake, coffee cake and other kinds. I checked there are many other branches one at Croydon, other at East Ham, Barkingside, South Harrow, Weblmbley, Rayners Lane and few other branches.
Highly recommended to visit.
