I get that craving for "American Lager", too, and I drink some of it every week. It seems like the system wants a break from the heavy beers and stouts sometimes.
Michelob Original Lager works for that. They claim they're brewing their original 1890 all-malt recipe to make it, and I think it's good. Then there's Sam Adams Boston Lager of course, and Boulevard Pilsner - also good ones.
Even with American Lagers, a fella's gotta have SOME standards. C'mon.
