ISO: Runbing and Banana Rolls

Hi all,

New here and hoping I can leverage the knowledge of all the foodies who frequent this site. I’m ISO of two specific items in the LA area.
(1) Runbing (潤餅) - I’ve found these Taiwanese street-style snacks at several 99 Ranch delis where they’re made to order. The ones at 99 Ranch are fantastic and cheap. Anyone else know where else I can find them? At a restaurant, perhaps?
(2) Banana rolls (香蕉糕) - This old school Cantonese snack is one of my favorites. I have asked multiple Cantonese bakeries both in SGV and Chinatown. No one has them. Anyone have leads?
