I am assuming the Coffee Shop is the what I call the Coffee Prince, and it is really good. It was one of the first ones I watched after BBF.

I first watched it on youtube then I bought it. The lead actress and actor in it are really good.

The Princess Hours(Goong) is probably the most like BBF. I think lots of BBF was actually taken from Princess Hours and improved on, but Princess Hours holds its on charm. The lead actor and actress in it are really good too(the same actress that is in the Coffee Prince.) The later parts of Princess Hours drags and there are times I get so mad at the characters.....but the ending is worth it.
