I've never been to Frank's but slaters is decent.
The slider there is off balanced to me. Don't get me wrong, I am probably one of the most carnivorous guys on this board but that beast has too much meat for me. Did I just admit that in public?
Since it isn't a far drive, I'd experience one for yourself though. You may like it. In fact, I guarantee you will but I think you can do better.
Have you ever tried cooking your own? I make some of the baddest sandwiches around to my taste. I get the meat:cheese:egg ratio right and get some awesome rolls to put it on. If I'm in the mood I'll add bacon and/or a hash brown. I also like my porkroll a little crispy so I slice it in varying thicknesses. I like the chew of the thicker middle slices and the crispy, cheesy outter bites. So the sandwich goes from one texture to a whole different realm as you get toward the middle.
I have a deli slicer so that is when you know you're a true pork roll and ribeye fan (cheese steaks) lol.
@joonjoon is in the ap area. He will have some good selections near you. Stay tuned!
