The Express Times in Easton PA has done a series on the Best Cheesteaks in the Lehigh Valley. The winner was Giacomo's in Easton. I've posted a link to the winning announcement.
The articles are not user friendly at all. I couldn't find a complete list of all the ratings, and you pretty much have to jump around various links to find all the places and reviews. Plus some are videos and others are writeups. On top of that it's apparently all the work of just two reporters.
Still in all, I've got a few new places to check out next time I get out that way. Oddly enough, the two real good cheesteaks I know of in the area, Zandy's and the Brass Rail, weren't among the 13 places they visited. http://www.lehighvalleylive.com/food/index.ssf/2011/06/cheesesteak_showdown_giacomos.html
