It's OK. They taste good but I don't believe the health claims. It might be healthier than McDOnalds but that's a pretty low bar.
I like roast beef on seasoned bread (herb or parmesan), lettuce tomato cheese mayo salt&pepper. I also like meatball sub and Italian sub. Their cheesesteak is among the worst three cheesesteaks I have ever had though.
The franchisee near me is kind of a jerk. He gets mad if I don't want chips and drink. Like dude, I'm not here for a complete experience, I'm here because I'm broke and hungry, and I can't make it to the grocery store. Just give me a cheap sandwich and quit glaring at me. Since he wants every order to be all or nothing, he gets nothing and I don't go there any more. He lost my business entirely.
