Great selection. HOWEVER, only the cheap beers I've never admit to drinking are kept in the coolers. So if you want local microbrews, seasonals, or even Blue Moon, you're going to want to leave time to chill the bottles before your next shindig.
Having only acquired a taste for beer while living in Tennessee--where beer can be bought in grocery stores, gas stations, and shady alleys--the prices seem steep to me. But I don't have much experience buying alcohol off-premise in PA, so I'm only deducting one star here.
There is a parking lot, but it's small and everyone parks crookedly, so good luck with that.
