I love Philadelphia: great city close to New York, with a fantastic food scene! Imagine that it is where there is the original Morimoto restaurant, where Marc Vetri has his amazing venue (review to come)! I will also mention the Reading Terminal Market, Sabrina's or Honey's for brunch!
But for sure, you cannot go to Philly without trying a Philly Cheesesteak! Now, there are many, many places serving this delicious sandwich, but not all of them are great. I remember that way back, we went to Philly with Jodi and a friend of mine from France, Malika. We found this amazing place close to the university that served us an amazing cheesesteak. It was not a popular joint and dinners were mainly students. Too bad that at that time I did not have the blog: no photo and no address! I then tried Geno's: this was fabulous! I remember the delicious bread and this incredibly tender meat. Then last year, we went to Geno's main competitor: Pat's King of Steaks.
