Uhmmm... well, yeah, Bro! Ain't the end of the world. I actually like film grain and digital noise, depending on the subject and light conditions. Did you notice the camera I used? The Canon A95 maxxes out at 400 ISO, and it was a fairly dark place. I took a ton of other shots over several various months in a few other similar venues, and much preferred the "flash off" hand-held slow shutter speed effects - noise and all. It's much more about atmospherics in places like these, and I just tossed all the shots with flash - they looked flat and uninteresting. In the end, I'd rather use as much available light as I can muster, very high ISO (depending on the camera,) and let the noise/grain fall where it may in exchange for additional sharpness. You may differ with this philosophy, and prefer your digital pics to have the smoothness of plastic, but I don't think that would have served this picture.
It just makes me thirsty looking at it, and I swear I can smell the hops...
