For being in the middle of nowhere (not even cel service) the Whip Tavern is great. A handful of quality English beers on tap, a few local (and rotating) brews AND a cask set-up combined with top notch English 'pub fare' make it a highly desireable stop.
They do a different 'special' each weekend, and the first weekend is Prime Rib which RAWKS.

The Half Moon Saloon in Kennett Square is another out-of-town eatery with a great menu and an outstanding draft selection.

Back in Philly, Yards brewery is open most days with a full selection on draft, and if you get lucky (which I haven't) you might be able to score a quick tour from one of the maestros.
