What alternative grains should I be eating, and does anyone have good recipes for them?

I'd like to branch out and try to eat grains other than wheat and rice. I've tried cooking with quinoa and bulghar...any other grains that you would recommend? And do you have any good easy recipe ideas for them?I live in SF so I always see lots of unusual grains in the bulk bins but I have no idea what to do with them. (p.s. I'm not a big fan of cous cous, but all others seem to be fair game).
