The sandwiches are pretty good, I believe I had the Ham & Swiss on my last trip there. The food portions are bigger than I can eat and the sandwiches are nice and melty. The shop itself is small- order at the counter and they'll call out when your order is ready.
SubFactory isn't my favorite sandwich shop, and I probably wouldn't ever pick this place to eat, but I wouldnt be opposed to going if someone else wanted to.
