Lotus leaf...where to buy?

Anyone know where I can buy those dried lotus leaves that are typically used in dim sum sticky rice. My 4 year old loves sticky rice, and I was hoping to make them (perhaps a little healthier version, which I guess he probably won't like as much). I imagine I could buy some in Chinatown, but just wanted to make sure before I made the trip.

I really like the flavor/aroma that they impart. Have bought them near Argyle at

Tai Nam
4925 N Broadway St # J Chicago, IL 60640-3056 - (773) 275-5666

I expect that you would find them at many Argyle and Chinatown markets.
