After reading all the reviews above, I want to say that The Slice of Heaven is a very nice place although it is small. It looks like one of your friends' home, it can make you feel comfortable.
Actually I am one of the waitress in the Slice of Heaven, I am a student in KMUST, the boss, Barbara is my former teacher. She is a very good person and boss, she always be friendly to all the guys. We can promise that all the ingredients is good and fresh. The price is reasonable. We buy the vegtables everyday. About the plastic bags, I want to say that we are trying our best to keep the food fresh. I think all the shop must use it more or less, and our food is kept as fresh as possible. We use the best milk to do all kinds of food, includes coffee, quiches, pies etc. Sometimes we waitress cook the food, maybe it is not very authentic, we are so sorry about that. Please come and have a loook, you will have a nice experience
