Hey!!
I work in Philly. Holt's is a rather great place. They have a nice lounge at the back of the shop. Even better is that they are opening an Ashton Cigar Bar upstairs from their store in about 3 weeks. There are a bunch of nice B&M's in that area as well.
There is also a nice place getting ready to open in the King of Prussia area in the next couple of months, "Cigar Mojo".
It also really depends where you are going to live and what school your going to. Many of the schools aren't really anywhere near Center City, but there is bound to a Cigar Shop somewhere around you.
