Todd English isn't TOOO far, but it's still a bit of a hike. Worth a look, plus if you can down a pint in less than 4 seconds, it's free.
You'll need the advice of a local though. If you're hell bent on a beer-tasting experience, you'll probably have to head off-strip somewhere. If you can't get a good answer before you go, just ask the cab drivers - they're pretty solid with advice.
