4:20pm coffee roll cake

Staying on the cheap and fabulous, Chinatown style roll cakes are a good choice.  At 95 cents from Fay Da, one of the fancier bakeries, you really can't go wrong.  The sponge cake is eggy and not too sweet, and the thin spread of cream is surprisingly salty, to add some serious interest.
