I had the best Stromboli in Philadelphia the other day. It was very cheesy, delicious, and only $6.50 for a small sausage Stromboli. Mind you, the small is actually huge. You might have to save the rest for later. I had this at Bellissima Pizza at Castor Avenue and Hartel Avenue.
There was a lot of ingredients in there so they were definitely not being cheap. Some pizza shops give you a little bit of toppings and not much cheese. I could barely finish the Stromboli even though I was very hungry for it. I doubt you can get that with fries and expect to eat everything in one sitting.
