In my experience, the Za'tar croissant is the big one. The good ones are so damn good...and you never see them outside Lebanon. The other one of note is a saaj (technically a man'ooshi 'al saaj, to use proper Arabic) with chocolate and halawa, which the rest of the world knows as halva, a sort of chunky sweet sesame confection. The chocolate is often replaced with nutella, making it all seem like a Lebanized crêpe. There's also the generic "rosto" which is a common sandwich or man'ooshi filling, which is just sort of western style roast beef cut in big chunks, as well as if memory serves, chicken rosto. There's also man'ooshi with mortadella and Président processed cheese, but these are abominations in my book.
