There's a burger stall in Kepong, somewhat near desa park city. It's called D Street cafe, and open till late night hours when all other shop close. The bun and ingredients and sauce they put like macam extra one.. taste really good and cheap. Burger ayam special (with egg) is RM3.80 and they have different variants/add-ons. The abang boss is also very friendly and humble.
