Cake Avenue at Kilat Centre (www.cakeavenue.com) does nice-looking cakes on order - you select the theme and can even specify all details of the design. The taste is o.k. and there is a lot of sugar and icing in various colours.
We used to live right above the shop and bought for our daughter's party. No business affiliation, just recommendation by a customer.
Smiling Orchid used to be good for cakes - I haven't used them for years though. Don't even know if they're still going but the should be, they were pretty popular. They have a website if they're still around.
