Wow. I can't believe a year went by before I found this place. Ginormous slices from full pies that they make exactly when they're needed. They don't have them chillin' in the front (or the back) like *some* other places. That means you might have to wait a little bit but you'll get a cheesy slice with any toppings you want that has a great flavor, crispy and soft crust exactly how I think of "New York Style" that you can fold and down with your favorite soda. They even give you a pizza slice to cut that massive slice down to size. $6 flat for a huge slice + drink. Slightly pricey but worth it in this case. Great place for a slice.
Avoid smaller pies - too doughy. Loses half a star for this. Also, extremely limited seating and service is lacking - high school / college students don't make the greatest hosts, but the food is good. That's what counts in my book.
Oh - Venezia's in Tempe has similar size slices for cheaper, but I get a stomach ache after eating there. So, J&Js wins even though it is pricier.
