Every once in awhile some local writer will undertake the challenge to find the best cheese steak in Philly. Here is another one for you to check out. I found it pretty accurate as I too find John's to be in a league of its own. Take note of his review of Geno's and Pat's and also note the emphasis on the importance of a good crusty roll. Also note that Chink's has opened a second site on Columbus Blvd right off of Christian St. Chink's is easy to find.
Have fun. Here it is: http://www.610wip.com/pages/351421.php
