Looking for a list of Gemara's that has lots of aggadic stories. The following can be excluded from the list- Avoda Zara and Perek Chelek in Sanhedrin.
Much of Bava Basra Perek 5 contains a whole slew of stories told by sailors and other people to different Amoraim. The Artscroll (and the book the juggler and the king) both explain these allegorically if you want it.
בבא מציעא - השוכר את הפועלים
From the beginning of the perek .דף פג
Ein Yaakov is a Sefer which consolidates all of the agadita from the Talmud on one place for easy access. There is some halacha for example it opens up with the beginning of meseches brachos. I think this is likely though because it still contains a story.
This will be the easiest place to find what you are looking for in one place.
