Perhaps Roti's best-kept secret is that instead of buying the larger red bean bun from their display at $0.60, buy the pack of 6 buns for $2.60 instead, amounting to an average of $0.43 each!! The buns in the pack are smaller, but no less generously-filled. In fact, because the filling tends to be on the sweeter side, I prefer the smaller buns which are less jelat than having a whole big bun filled with sweet red bean paste.
