Just do this: go to Jersey Mike's, (I like this location particularly), go and order a #56. Steak, mushroom, jalapenos, some kind of cheese that just makes the whole sandwich a chessey, delicious mess! FANTASTIC!
By the way, I went to Jersey Mike's website, had a bit of difficulty but got 2 responses from Mike's: management AND franchisee. Nice. They care.
WHAT A GREAT SANDWICH!
