Malvern is the home of The Flying Pig, one of the greatest places on Earth. (as noted by the groom). They have a fantastic draft list as well as bottle selection.
The bride recommends:
*King Street (downtown Malvern)-houses multiple restaurants, bars, and a Wawa
*Wayne, PA-North Wayne is a cute little town close to Malvern and also where we were engaged!
*King of Prussia-site of one of the largest malls + tons of restaurants
*The Grove Malvern-right across from the Desmond and location of pubs + restaurants
*Valley Forge Park-nice place to hike (for all the outdoor lovers)
People's Light and Theater has a good list of some other things to do as well!
