We got the "Big Boss" and "Phat Philly". The two seemed to be pretty much the same thing - just meat and toppings you choose, but Phat Philly had additional fries in it.
I came in with high expectations, so I wasn't too amused. It tasted fine, but it was so stuffed that it was impossible to take bites of. I ended up using a fork to eat it piece by piece (kind of defeats the purpose of a sandwich).
Overall - great experience, but I wouldn't come regularly! I wasn't full after eating this $10 sandwich.
