618 Sim Carrot Cake is located in a quiet neighborhood at Yishun near Khatib MRT Station. The stall sells white carrot cake ($3/$4) while giving customers the option to add prawns ($4.50/$6). They used to sell the black version as well but not anymore.
I ordered the smallest $3 plate and was given a buzzer after I paid up. According to online reviews, I was mentally prepared to wait for up to an hour but all it took was about ten minutes for my buzzer to start vibrating.
I was astonished to see the portion of my $3 carrot cake on the counter, ready for collection. I thought the auntie has made a mistake and had given me the $4 plate instead. I double checked with her and she assured me that it is indeed my order.
The generous portion can actually be shared among two persons which is totally value for money!
