Where am I?

The size of the room is as wide as putting our 6 classes together. The light is orange and not strong. The place is in the mood, but it is so noisy because there are a lot of people and music is playingin there. If someone enters in that place, a person can see a refrigerator on your right side. There are cakes and sandwiches in it. At the back of the refrigerator, we can see a menu on the wall. Then, you walked in more and you can find a counter next to refreige. On the counter,there is a big square silver machine. The machine makes a noise like a steam locomotive. Black uniformed people make something continuously with that machine and milk. They draw some pictures like heart and leaves using milk in a third-half-filled cup with espresso.
