I've recently moved to Boulevard Park from the East Coast and was so lucky to come across this pizza place. If you're looking for NY/Philadelphia style pizza in the Seattle area, you must stop here!
There's never a wait, the staff is super friendly, and prices are fair. They also run some great specials. Make sure you try the bread sticks :)
This place deceivingly looks like a hole in the wall establishment (no where to sit), but don't let that fool you. I can't say enough about Pizza Source. I'm so glad that I can get a little taste of home here on the West Coast!
