Yes it is a chain, but I don't see that as a negative for this place.
I love the chicken teriyaki is my favorite. I like the the sandwich is hot, the meat and veggies are cooked on the flat top to order. The bread (only white) is fresh. They have many selections as well as a build your own.
Their fries are great, fried in peanut oil and the large is big enough for two hungry guys to share easily.
I'm from KC and there aren't many sub shops like this around our parts that cook the meat hot on a flat top. I much prefer this to the cold cut subs which they do also serve here.
