I seriously doubt you would find Jian Bing in the I-District. Jian Bing is street food, and all of the restaurants in the ID serve sit-down food.
Here is the link to an earlier Road Food discussion (with video courtesy of YouTube): http://www.roadfood.com/Forums/topic.asp?TOPIC_ID=16537
Also, you might consider posting your question on Chow Hound. The audience there is a little different. I found a thread on it here: http://www.chowhound.com/topics/304640
Good luck with your search, and please let us know if you find any place state-side!
