There are quite a few American brews I like but I usually stick to MGD and if I find somewhere that actually have in on draft even better (Black Angus chain do).
Micro Breweries are another thing, it's a great experience! For those of you who may not have tried one yet, they offer a sampler which is a tray of small glasses (usually a little bigger than a shot glass) of each of their brews for you to try. The idea being you can choose the one you prefer without paying for and wasting full measures that you may not like. You can of course just have another tray of samplers

I remember one time in San Antonio, I think it was, where they had a maple ale, it was surprisingly good.
I can recommend Taps at Brea eastern LA, great food there too
