Good and cheap Malaysian food are hard to come by in London. There are a couple - for example Malaysian Hall in Bayswater area is run by the Malaysian government, and Malaysian Deli in our very own Brockley. But Roti King does something that neither of those does - proper roti canai.
Roti canai is a type of fluffy flat bread sold in Malaysia, an is normally eaten as a side with curry or dhal (lentil) sauce. It is a versatile dish, and can be combined with other ingredients like eggs and meat, but the best is still the plain ol kind. It is light and fluffier that the kind of flatbread that are normally served in Indian restaurants in this country. When I used to live in Malaysia, I would have it for breakfast, lunch an occasionally, dinner.
