I was assuming that she wanted it for home. Also Salima on MLK in south seattle has a pretty good version of Roti Canai. Actually this is a very underrated restaurant.
Yes, I mean, besides Malay Satay hut. Theirs is quite good, but one roti canai pancake and 1/4 cup of curry gravy for $3.50 is a lot of money for a little snack.
A lot of times it may be called roti canai. Also you can buy paratha which is an indian flat bread. It should be pretty cheap so you can buy a few brands and see which one you like best.
