I haven't had wheat grass, but I've had wheat grass juice for the first time recently. The taste is "different" but I wouldn't describe it as bad. It's supposed to be very healthy (and, oddly enough, gluten free). It's very concentrated, so you get a shot of it instead of a whole glass. I've only had it a couple of times (including today at lunch), so it's too soon to tell as far as results or anything. I've seen the grass itself in the health food store, but I think you need a juicer to get the juice out, and a juicer isn't in my budget right now.
