If you're working on a case headed for oral arguments before the Third Circuit, then a trip to Philadelphia (if you're not already based there), is in store for you. I spent five years of my life in the City of Brotherly Love -- four years as an undergrad, and one year as a judicial clerk -- so I thought I'd share some things to do while you're in Philadelphia.
I haven't lived in Philly since 2000, and yes, I am still missing Philly cheesesteaks. Now, most Philly guides will tell you that you need to go to Pat's or Geno's in South Philly -- they are wrong. I really don't know what all the fuss is about, I tried 'em and didn't like 'em.
My personal favorite is Jim's Steaks, and a truly good combo is beef (or chicken), mushrooms, onions and provolone. If you're more of a fine dining person, be sure to check out Laurel, Nicholas Elmi's (a/k/a the newest winner of the title "Top Chef") restaurant.
