I order food from Frank's about once a month, but I always take it home. They make the best pizza in the South Edison area. The Italian presence, like many restaurants, has given way to a dominantly Latino cooking staff, but don't be fooled - these guys know how to cook well - very well. I have ordered a variety of different sandwiches, pastas, pizza, calzones, and entrees... while they may not be authentic Italian, they make great food.
Unfortunately, it seems the owners have not visited this branch in quite some time. The interior is in dire need of an update. Even if it's just a pizzeria (which it isn't) someone needs to clean up the place and bring some life back to it. Otherwise, call them up and place an order - you won't be disappointed. Large pie w/ works is amazing.
