The first one is "po-lo-yau" (pineapple bun), famous must have breakfast-bun in most of the Hong Kong's "Cha-Chan-Teng" (like kopitiam in Malaysia). The "po-lo-yau" is in very soft texture with a thin slice of cold butter filling inside. But normally you can't feel the cold butter anymore as its all melts after filling into the piping hot bun.
The second one is "sai-doll-si" (western toast), you would like this if you love peanut. It has thin filled of peanut jam in between 2 slices of bread and put them inside the beaten egg before "fried" it. It's served with butter and honey, the butter would melt since the bread is piping hot, pour some honey on the top of the bread and it tastes heavenly.
These buns are in high-calories types, so if you are on-diet, think twice before you take, but i don't think you can resist it. Just imagine you can sip on the hot/cold "si-mart-nai-cha" (something like teh tarik in Malaysia) at the same time you gobble down the bun. Hmm...nothing can compare..just like you have Nasi Lemak with Nescafe Ice as your breakfast...suddenly i so miss those days i was in Malaysia...
"po-lo-yau" - RMB3
"sai-doll-si" - RMB10
"si-mart-nai-cha" - RMB8(hot), RMB10(with ice)
