I have been buying a lot of cakes from Cat & The Fiddle lately.. For birthdays, gatherings, etc. Their cakes are quite affordable and very yummy. Every now and then there's some promotion going on so you can search for coupons online.
The delivery fee is $9.90 per location for orders below $120. We usually go and self-collect cos it's not too far from our place.
Directions to their office can be found on their website. It is very near Tai Seng MRT station.
