Go for The Bobbie, which is essentially Thanksgiving dinner on a sub. The Capastrami (hot pastrami and Swiss) also good. If you're REALLY hungry, go for the 20" sub.
Bread is a bit too doughy for my tastes.
Veggie cheesesteak is good but get mayo otherwise its a bit dry
Get the chicken cheese steak!
