Does anyone know of any "ethnic" grocery stores in Jerusalem - particularly ones carrying Asian products?

I'm a graduate student studying at Hebrew University in Jerusalem, and for the last 6 months, I've been feeding myself on 50 NIS a week. I'd like to change up my food routine a little bit and was hoping for some great suggestions on the best food deals in Jerusalem ... every shekel counts!

Thanks!

There's an Arab restaurant across the street from the Damascus Gate that's really fantastic. Go to the take out counter next to the restaurant proper for great falafel for only 6 NIS. The shawarma, however, is not good.
